Exam 3 (cont.) 19. 8 of 12 Consider two carts of mass m and 4m, at rest on a frictionless, horizontal surface. Now suppose a horizontal force is exerted on each cart. The forces are constant, and they have the same magni- tude F, and the same direction. The force on m acts for 2 seconds and the force on 4m acts for 1 second. After the forces cease, the carts continue moving with constant velocity forever. Compare the momenta...

I have a question about my physics worksheet. 2. Two collision experiments are performed with a small clay ball and a wooden rod in a frictionless, weightless environment. The ball and the rod are not in contact with any other objects. Each has the same mass. In both experiments, the ball initially has speed v0 and moves without spinning to the right toward a rod that is initially at rest. The ball sticks to the rod in each case. In...

to block B via string 2, as shown.
For this problem, assume that neither string stretches and that
friction is negligible. Both blocks have finite (nonzero) mass.

Earlier in the course we introduced the constant acceleration formulas (kinetic equations) vo,=at, x=xo +vot +1/2at2, ect, which are valid when the acceleration vector of mass m is constant. For which of the following two situations is the acceleration vector constant so that these formulas are valid? I.) A satellite of mass m in circular orbit of radius R around a planet of mass M. II.) A mass m is released from rest at a point in space 32,000 km...
