*44. GO A 60.0-kg person, running horizontally with a velocity of +3.80 m/s, jumps onto a 12.0-kg sled that is initially at rest. (a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away. (b) The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow?
(c) A 2.00 kg block hangs from the end of a 1.50 kg, 1.00 m long rod, togat her forming a pendulum that swings from a fridionless pivot a the top end of the rod. A 10.00 g bullet is red horizontal into the block, where it sticks, causing the pendulum to swing out to a 30:00 angle as shown in Figure 5. Calaulate the initial speed of the bullet and leave your answer in terms of ! 1.

A 35 g steel ball is held by a ceiling-mounted electromagnet 3.4 m above the floor. A compressed-air cannon sits on the floor, 5.0 m to one side of the point directly under the ball. When a button is pressed, the ball drops and, simultaneously, the cannon fires a 25 g plastic ball. The two balls collide 1.2 m above the floor. What was the launch speed of the plastic ball?
5) Assume a perfectly plastic impact as the 5-kg body falls from a height of 2.6 m onto a plate of mass 2.5 kg. This plate is mounted on a spring having a spring constant 1772 N/m. Neglect the mass of the spring as well as fric- tion, and compute the maximum deflection of the spring after impact. 2.6 m 5kg 2.5 kg K = 1772 N/m
1. Parcels are moved via conveyor with velocity vo down to a colinear incline that is static at point A where sliding begins. The parcels eventually fall off at point B, which is 7.0 m past A. If the coefficient of kinetic friction on the incline is 0.40, find the velocity of the conveyor belt, vo, such that the parcels have zero velocity at point B. 7m 15°
