A train car of mass mị rolls down a hill, starting from rest from a height h; above the valley floor. At the bottom of the valley, car m1 bumps into a second car of mass m2 that has been standing there. The two cars lock to each other and jointly start climbing up the hill on the other side of valley, until they momentarily come to rest at a height hf above the valley floor. Assuming you can neglect friction, what is the ratio between m2 and m1 if hf = h;/9? Check: For hf = hi/16 you should find m2 = 3m1. Hint: Analyze this problem in three stages. The middle (second) stage will be the collision of the two train cars; from right before to right after they collide.

Two spheres of masses m = 1.07 g and m' = 1.10 * 10 ^ 2 kg are isolated from all other bodies and are initially at rest, with their centers a distance r = 14 cm apart.

Two blocks, which can be modeled as point masses, are connected by a massless string which passes through a hole in a frictionless table. A tube extends out of the hole in the table so that the portion of the string between the hole and M1 remains parallel to the top of the table. The blocks have masses M1 = 1.4 kg and M2 = 2.1 kg. Block 1 is a distance r = 0.85 m from the center of the frictionless surface. Block 2 hangs vertically underneath. a) Assume that block two, M2, does not move relative to the table and that block one, M1, is rotating around the table. What is the speed of block one, M1, in meters per second? b) How much time, in seconds, does it take for block one, M1, to make one revolution?
A tire is tied to a rope that is tied to the branch of a tree so that the tire swings in a circular trajectory of radius h1 = 15.31 m. A child takes the tire to the top of a platform that is a height h2 = 12.60 m above the ground, sits in the tire, and swings from rest from the platform. The combined mass of the tire and child is 36 kg. The rope is taut when the child leaves the platform and you may neglect the mass of the rope. At the bottom of the circular trajectory, the child and tire are a height h3 = 0.99 m above the ground. include a diagram showing the physical sites (a) Calculate the speed of the child/tire at the bottom of the circular trajectory. m/s (b) Calculate the maximum tension in the rope as the child/tire swing back and forth.

A massless spring of constant k =78.4 N/m is fixed on the leftside of a level track. A block of mass m = 0.50 kg is pressedagainst the spring and compresses it a distance d, as in FigureP7.74. The block (initially at rest) is then released andtravels toward a circular loop-the-loop of radius R= 1.5 m.The entire track and the loop-the-loop are frictionless, except for the section of track between points A and B. Given thatthe coefficient of kinetic friction between the block and thetrack along AB is μk = 0.30 and that the length of AB is 2.5 m,determine the minimum compression d of the spring thatenables the block to just make it through the loop-the-loop atpoint C. Hint: The force exerted by the track on the block willbe zero if the block barely makes it through the loop-the-loop.
A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley. Block A, which has a mass of 5.723 kg is connected to one side of the rope. On the other side, Block B, with a mass of 12.602 kg is connected. The system is released from rest. What is the speed of block B, after B has traveled 0.716 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
A binary star system has two stars, each with the same mass as our sun, separated by 6.00×1011 mm . A comet is very far away and essentially at rest. Slowly but surely, gravity pulls the comet toward the stars. Suppose the comet travels along a straight line that passes through the midpoint between the two stars. What is the comet's speed at the midpoint?
A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 99.5 kg. The mass of the rock is 0.277 kg. Initially the wagon is rolling forward at a speed of 0.488 m/s. Then the person throws the rock with a speed of 16.6 m/s. Both speeds are relative to the ground. Find the speed of the wagon after the rock is thrown (a) directly forward in one case and (b) directly backward in another. (a) vi (b) v-
You and your family take a road trip on a long holiday weekend. In a certain section of the trip where the road is particularly uneven, the car goes over a bump that is curved downward with a radius of 23.0 m. See diagram below. The mass of the car and its passengers is 1100 kg. (a) When the car is at the highest point of the bump its speed is 7.35 m/s. Determine the magnitude, in N, and the direction of the force exerted by the road on the car at this highest point. magnitude |N direction ---Select-- (b) If the speed at the highest point is above a certain maximum value the car will lose contact with the road. Calculate this maximum speed in m/s. m/s
In the figure, a man is trying to get his car out of mud on the shoulder of a road. He ties one end of a rope tightly around the front bumper and the other end tightly around a utility pole 29 m away. He then pushes sideways on the rope at its midpoint with a force of 550 N, displacing the center of the rope 0.28 m from its previous position, and the car barely moves. What is the magnitude of the force on the car from the rope? (The rope stretches somewhat.)
A meter stick has a center of mass at the 50 cm mark. Using two fingers, one at the 20 cm mark and the other at the 30 cm mark, you hold the meter stick in a horizontal, stationary position. Given the force at the 20 cm mark is 2 N, find the mass of the meter stick.
You want to speed up the system of rotating disks. To do this, you throw a ball of mass mb at the two disks that are still rotating together with the same speed (just after they collide). You throw the ball at the disks, and the ball follows the following trajectory as viewed from above. The ball of mass mb approaches the disks at an angle θ with respect to the tangent line to the disk and rebounds at an angle ϕ with respect to the normal. The ball's initial speed is v_0, and its final speed is v_f. What is the new z-component of the angular velocity of the system of rotating disks (they still rotate together) after the collision with the ball? Use these values for the parameters (associated with image 1): v_f=2.13 m/s v_0=14.2 m/s θ=63.2∘ ϕ=68.7∘ m_b=1.59 kg R=2.68 m *Initial scenario if it helps* Two disks are initially spinning, one above the other on a small axle that provides a small, but non-negligible torque from friction, as shown in the figure below.
