If we immerse an empty box of mass m = 3.8 kg in water, we see that it comes up with an acceleration of a = 2.9m/s2. How much sand do we need to fill the box to make it go down with the same acceleration?

A spherical bowling ball with mass m = 3.8 kg and radius R = 0.106 m is thrown down the lane with an initial speed of v = 8 m/s. The coefficient of kinetic friction between the sliding ball and the ground is p = 0.33. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down...

A box of mass M = 0.2kg starts out at rest on a horizontal table. The surface is not frictionless. At t = 0.75s you start pushing on the box horizontally in the +x direction, causing it to speed up. The force you push with is not necessarily constant. You stop pushing on the box at t-2s, after which it slides on its own as it slows down and comes to rest at t = 4s. Between t-2s and t...
