Atennis ball traveling horizontally at a speed of 40 m/s hits a wall and rebounds in the opposite direction. the time interval for the collision is about 0.013 s, and the mass of the ball is 0.059 kg. assume that the ball rebounds at the same speed.
(a) determine the initial and final momenta of the ball. assume the initial velocity direction is positive.
(b) determine the change in momentum of the ball.
(c) determine the average force exerted by the wall on the ball.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
