Question

A soccer player strikes a soccer ball with a force of 550 N. If the player and the ball remain in contact for 0.03 s. What impulse was delivered to the ball by the player?

Answer 1

Easy my dude.
Impulse (J) is equal to the change in momentum of the ball. It is also equal to Force times Time:
J = Ft
J = (550 N)(0.03 s)
J = 16.5 Ns
