Students work together during an experiment about Newton’s laws. The students use a setup that consists of a cart of known mass connected to one end of a string that is looped over a pulley of negligible friction, with its other end connected to a hanging mass. The cart is initially at rest on a horizontal surface and rolls without slipping when released. The inertia of the cart's wheels is negligible. Students have access to common laboratory equipment to make measurements of components of the system. By collecting the appropriate data, the students can determine the relationship between the acceleration of the cart and the net force exerted on the cart. Which of the following graphs should the students produce to show the correct relationship?

Consider two objects with m 1>m 2 connected by a light string that passes over a pulley having a moment of inertia of I about its axis of rotation. The string does not slip on the pulley or stretch. The pulley turns without friction. The two objects are released from rest separated by a vertical distance 2h. Use the principle of conservation of energy to find the translational speeds of the objects as they pass each other.
A solid circular disk has a mass of 3.75 kg and a radius of 0.379 m. Each of three identical thin rods has a mass of 0.646 kg. The rods are attached perpendicularly to the plane of the disk at its outer edge to form a three-legged stool (see the figure). Find the moment of inertia of the stool with respect to an axis that is perpendicular to the plane of the disk at its center. (Hint: When considering the moment of inertia of each rod, note that all of the mass of each rod is located at the same perpendicular distance from the axis.)
Can you draw a free-body diagram of this problem? Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center, and a very light board 3.2 m long as shown in the figure. Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?
A sphere of mass 1.0 kg and radius 1.5 m is attached to the end of a massless rod of length 1.5 m. The rod rotates about an axis that is at the opposite end of the sphere (see below). The system rotates horizontally about the axis at a constant 372 rev/min. After rotating at this angular speed in a vacuum, air resistance is introduced and provides a force 0.33 N on the sphere opposite to the direction of motion. What is the power (in W) provided by air resistance to the system 107.0 s after air resistance is introduced? (Enter the magnitude.)
I'm struggling to understand how to do this: A block of mass m1 = 1.55 kg and a block of mass m2 = 6.05 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of θ= 30.0°. The coefficient of kinetic friction is 0.360 for both blocks. Use g=9.8 m/s2. (a) Determine the acceleration of the two blocks. (Enter the magnitude of the acceleration.) (b) Determine the tensions in the string on both sides of the pulley (left side and right side).
Round off 2 decimal places. Input magnitude only.

A motorcycle with a 200 kg body has two 20 kg wheels with 40 cm radii (whose mass distribution is not known).

Vlad needs to draw water from a deep well. He is using a bucket that is connected by rope (negligible mass) to a wooden axle at the top of the well. By cranking a handle at the end of the axle, Vlad is able to unwind the rope around the axle and move the bucket downward. The radius of the axle is R = 30 cm. The bucket is traveling downward at speed vi = 25 cm/s when the handle slips out of Vlad’s hand. As the rope unwinds and the bucket falls downward, the axle spins freely with an angular acceleration whose magnitude is α = 4.5 rad/s^2. The bucket falls through a distance of d = 7.0 m before crashing into the water. 1. What is the angular speed ωf of the axle when the bucket first hits the water? 2. As d → 0, what limit does ωf approach and why?
