Question

A 0.060-kg ice hockey puck comes toward a player with a high speed. The player hits it directly back softly with an average force of 1.50 x 10^3 N. The hockey stick is in contact with the ball for 1.20 ms, and the ball leaves the stick with a velocity of 8.00 m/s. Let the direction of the force be the + x direction. Find the following (note: be careful with the sign/direction of the values):_______. 1. The final momentum of the ball 2. The impulse on the ball 3. The initial velocity of the ball

Explanation:

Given

mass of puck Average force time of contact puck leaves with a velocity of We know impulse is $$=\text{change in momentum}$$

therefore   Final momentum   Impulse on the ball Impulse Initial velocity is given by  i.e. initially ball is moving towards -x-axis
