A ballistic of mass m = 100 g is traveling at a speed v towards a box of mass M = 1 kg sitting at rest. The ballistic collides with and sticks to the box, and the two move as a single body with a speed v1 along a rough, horizontal surface. The coefficient of friction between the box and the surface is μk = 0.33. Following the collision, the two objects travel a distance D = 8 m before coming to rest. See the figure below. Part (a) Is the mechanical energy of the ballistic-box system conserved during the collision? Defend your reasoning with a conceptual argument. Part (b) Determine the initial speed v at which the ballistic was traveling. For this question, you must use the concepts of work, energy, and momentum in order to receive full credit. Part (c) Suppose instead, after the collision, the ballistic-block system slides up an incline (μk is still 0.33). In order for the ballistic-box system to still travel a distance of 8 m, would the ballistic's initial speed need to be larger or smaller? You should provide a conceptual argument; no math or calculations are necessary.

A 2-kg object, moving at 1 m/s, collides with a 1-kg object that is initially at rest. After the collision, the two objects are found to move away from each other at 1 m/s. Assume they form an isolated system. (a) What are their actual final velocities in the Earth reference frame? (b) What is the velocity of the center of mass of this system? Does it change as a result of the collision?

An object of mass m starts from the left with velocity v0 and travels along a track moving right from position 1 to position 5 as shown. The track is completely frictionless, except for a horizontal region of length Δxf, where the coefficient of kinetic friction between the track and the object is μk. The object finally collides with a spring with a spring constant k and comes to rest in position 5 , compressing the formerly relaxed spring by a maximum amount, Δx. Which statements about the mechanical energy of the object-earth-spring system as the object moves from position 1 to position 5 is FALSE? Assume that the center of mass of the block is at the exact same vertical heights as positions 1, 3, and 5 . Note that while the object is moving at positions 1 through 4, the magnitudes of the velocity vectors shown may not be to scale. Note that more than more than one statement might be false (unlike what you will see on the final exam, where you will only be able to select a single response). The potential energy is the same at positions 1, 3 , and 5 . The gravitational potential energy is the same at positions 1, 3, and 5 . The total mechanical energy is the same at positions 1, 2, 3, 4, and 5. The kinetic energy is the same at positions 1 and 3 . The total mechanical energy is the same at positions 4 and 5 . The total mechanical energy is the same at positions 1, 2 , and 3.
