Question

A player bounces a 0.46-kg soccer ball off her head, changing the velocity of the ball from v⃗ i = (8.4 m/s )x^ + ( -2.3 m/s )y^ to v⃗ f = (5.9 m/s )x^ + (3.0 m/s )y^.

If the ball is in contact with the player's head for 6.7 ms, what is the direction of the impulse delivered to the ball?

What is the magnitude of the impulse delivered to the ball?

Answer #1

*e know that impulse of the ball*

A soccer ball of mass 0.30 kg is rolling with velocity 0, 0, 3.0
m/s, when you kick it. Your kick delivers an impulse of magnitude
1.6 N · s in the −x direction. The net force on the rolling ball,
due to the air and the grass, is 0.28 N in the direction opposite
to the direction of the ball's momentum. Using a time step of 0.5
s, find the position of the ball at a time 1.5 s...
