The average force provided to the bullet during the time of contact is 1200 Newton. a. Calculate the time of contact with the hand before the bullet comes to rest. b. Calculate the work done by the hand in bringing the bullet to rest. c. Calculate how far back the hand has been displaced. d. Calculate the change in the kinetic energy of the bullet.

Review. There are (one can say) three coequal theories of motion for a single particle: Newtons second law, stating that the total force on the particle causes its acceleration; the workkinetic energy theorem, stating that the total work on the particle causes its change in kinetic energy; and the impulsemomentum theorem, stating that the total impulse on the panicle causes its change in momentum. In this problem, you compare predictions of the three theories in one particular case. A 3.00-kg object has velocity 7.00jm/s. Then, a constant net force 12.0iN acts on the object for 5.00 s.

A 44.0-kg child finds himself trapped on the surface of a frozen lake, 10.0 m from the shore. The child slips with each step on the frictionless ice and remains the same distance from the shoreline. Egged on by his parents, he throws a 0.750-kg ball he is carrying toward the center of the lake with a horizontal speed of 1.50 m/s, in the direction opposite that of the shoreline. a. Does the act of throwing the ball cause the child to move? If so, what are the speed and the direction of his motion with respect to the Earth? b. What are the forces acting on the child when he throws the ball?
