(a) In that 3.0 s interval, how much work is done on the object by theforce accelerating it? What is the instantaneous power due to that force (b) at the end of the interval and (c) at the end of the first half of the interval?

Two billiard balls, A and B, of equal mass (150 g) move at right angles and meet at the origin of an xy
coordinate system. Initially, ball A is moving along the y axis at +2.0 m/s, and ball B is moving to the
right along the x axis with speed +3.7 m/s. Both balls collide and after the collision, the second ball,
B, moved along the positive y axis. (a) What is the final direction of ball A? (b) What are the speeds of
the two balls after the collision? (c) Considering the balls to be an isolated system, what is the net
impulsive force resulting from the collision if the impact lasted for 0.4 sec? (d) Does your answer to
part c make sense, explain?

In order to convert a tough split in bowling, it is necessary to strike the pin a glancing blow as shown.
Assume that the bowling ball, initially traveling at 13.0 m/s, has five times the mass of a pin and that
the pin goes off at 75° from the original direction of the ball. Calculate the speed (a) of the pin and (b)
of the ball just after collision, and (c) calculate the angle, 0, through which the ball was deflected.
Assume the collision is elastic and ignore any spin of the ball.

A bullet of mass m moving with velocity v strikes and becomes embedded at the edge of a cylinder of
mass M and radius Ro, as shown. The cylinder, initially at rest, begins to rotate about its symmetry
axis, which remains fixed in position. Assume no frictional torque. (a) What is the total moment of
inertia after the collision? (b) What is the angular velocity of the cylinder after this collision? (c) Is
kinetic energy conserved (ignore the motion of the cylinder's center of mass)? (d) Assume that the
cylinder rotated for t sec before coming to a stop, what is the angular acceleration of its motion? (e)
What is the toque resulting from the force of impact which caused the rotation? Icyl = 0.5 M Ro²
