youth soccer ball size 3
HELP FOR PHYSICS, PLEEAASEE!!?
Recent studies have raised concern about `heading' in youth soccer (i.e., hitting the ball with the head). A soccer player `heads' a size 3 ball deflecting it by 52.0°, and keeps its speed of 13.00 m/s constant. A size 3 ball has a mass of approximately 2.000 kg. What is the magnitude of the impulse which the player must impart to the ball?
Picture the ball coming in at 26 deg. from vertical at 13 m/s.
It is deflected back at 26 deg. from vertical but 180 deg. from its incoming direction.
Its vertical velocity is 11.7 m/s coming down and 11.7 m/s going up.
Its horizontal velocity is 5.7 m/s and is unchanged by the bounce.
The deflection changes the ball's direction by 52 deg.
The impulse imparted to the ball is 2.00(23.4) = 46.8 N s
