A pulley device is used to hurl projectiles from a ramp (mk = 0.26) as illustrated in the diagram. The 5.0-kg mass is accelerated from rest at the bottom of the 4.0 m long ramp by a falling 20.0-kg mass suspended over a frictionless pulley. Just as the 5.0-kg mass reaches the top of the ramp, it detaches from the rope (neglect the mass of the rope) and becomes projected from the ramp. %3D

Two objects ( m1 = 5.00 kg and m2 = 3.00 kg) are connected by a light string passing over a light, frictionless pulley as in Figure P5.71. The 5.00-kg object is released from rest at a point h = 4.00 m above the table. (a) Determine the speed of each object when the two pass each other. (b) Determine the speed of each object at the moment the 5.00-kg object hits the table. (c) How much higher does the 3.00-kg object travel after the 5.00-kg object hits the table?
A basketball player of mass m=88.4 kg jumps straight up for a ball. To do this, he lowers his body d1=0.44 m, then he accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a speed sufficient to carry him d2=0.56 m above the floor. Write an expression for the speed v with which the basketball player leaves the floor. Write an expression for the speed v with wiich the basketball player leaves the floor. Write an expression for the acceleration, a, of the basketball player during the leg-straightening. Write an expression for the force upward force, FN, exerted on the basketball player by the floor during the leg straightening. What is the magnitude, in newtons, of the force FN while the player is straightening his legs?
Kyle, a 95.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.538 meters off the ground. He hits the ground 0.0333 metersaway from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: ? m/s
My sister Crystal of mass M1=50kg is on an ice covered sidewalk with her dog Buster, who has mass M2=38kg. They are initially distanced d=5.00m apart. By pulling on the massless leash, my sister exerts a constant force F=30.00N on Buster, Buster slides towards her. How fast is Buster moving when he and my sister meet? (The leash is not rigid, so the distance can change between them. They also end at the same point, which means even if you cannot solve for their position, you can set them equal to one another)
=Two blocks are connected by a light string that passes over a frictionless pulley as shown. The block of mass m₁ = 0.95 kg lies on a horizontal surface and is connected to a spring of force constant 30 N/m. The system is released from rest when the spring is unstretched. The hanging block of mass m₂ 0.5 kg falls a distance of 0.10 m before coming to rest. Calculate the coefficient of kinetic friction between the mass m, and the horizontal surface.

A stationary 2.17-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bt 2, where t is the time in seconds from the instant the stick first contacts the object. If a = 1,500,000 N/s and b = 20,000,000 N/s?, what is the speed of the object just after it comes away from the stick at t = 2.55 x 103 s? %3D
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.)
Two blocks of mass m1 = 0.6 kg and m2 = 2.4 kg are connected by a massless string, as shown in the Figure. They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.27. Calculate the speed of the blocks after they have moved a distance 53 cm. Assume that the pulley is massless and frictionless.
