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.

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 5.40 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. Figure 1 of 1 m = 0.200 kg Part A What is the coefficient of kinetic friction on the horizontal surface? Submit Request Answer Part B How much work is done on the package by friction as it slides down the circular arc from A to B ? Express your answer in joules. Submit Request Answer

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?
