Homework Statement
1. A 300g handball moving with a speed of 5 m/s strikes the wall at an angle of 40 degree and then bounces off with the samw speed at the same angle. It is in contact with the wall for 2ms. What is the average force exerted by the ball on the wall ??
2. A handball of mass 300g is thrown straight against a wall with a speed of 8 m/s. It rebounds with the same speed. (a) What impulse is delivered to the wall ? (b) If the ball is in contact with the wall of 0.003 s, what average force is exerted on the wall by the ball ? (c) The ball is caught by a player who brings it to rest. In the process, her hand moves back 0.5m. What is the impulse received by the player ? (d) What average force was exerted on the player by the ball ??
Homework Equations
p=mv, I=[tex]\Delta[/tex]p
The Attempt at a Solution
I don't know if the bouncing will affect anything ?
1. I am clueless since the ball hit at 40 degree angle.
2. For (a) I did I=[tex]\Delta[/tex]p and get I=0.3 * 8=2.4 N. Am I right ??
