5- A 0.05-kg bullet is moving to the right with a speed of 450 m/s when it strikes a 20 kg box of sand that is also moving to right with a speed of 5 m/s. The kinetic coefficient of friction between the box and the horizontal surface is μk = 0.30. Determine the speed of the bullet-box unit when the bullet becomes embedded in the box of sand, and the distance that the unit moves before coming to rest.

A box of mass m = 9.00 kg is located at the top of a ramp of height h = 7.00 m, as shown in the figure. The coefficient of kinetic friction between the ramp and the box is μk = 0.6. You give the box a push so that it starts sliding down with an initial speed of 2.50 m/s. The box continues its motion on a rough horizontal surface for 15.00 m until it hits a spring of spring constant k = 300. N/m and fully compresses it by 50.0 cm before coming to rest. What is the coefficient of kinetic friction between the horizontal surface and the box?

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 1.40−kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Figure a). The object has a speed of v1 = 3.30 m/s when it makes contact with a light spring (Figure b) that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance d (Figure c). The object is then forced toward the left by the spring (Figure d) and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest a distance D to the left of the unstretched spring (Figure e). (a) Find the distance of compression d (in m). m (b) Find the speed v (in m/s) at the unstretched position when the object is moving to the left (Figure d). m/s (c) Find the distance D (in m) where the object comes to rest. m (d) What If? If the object becomes attached securely to the end of the spring when it makes contact, what is the new value of the distance D (in m) at which the object will come to rest after moving to the left? m
