Not what you're looking for?

A man kicks a 200g ball such that it leaves the ground at an angle of 30 deg. with the horizontal and strikes the ground at the same elevation a distance of 15m away. Determine the impulse of his foot on the ball. Neglect the impulse caused by the ball's weight while its being kicked.

**answer should be 2.61 N*s**

##### Solution Summary

The solution calculates impulse of a foot kicking a soccer ball.

##### Solution Preview

Let the velocity of the ball after being kicked be v

ball leaves the ground at an angle of 30 deg

Therefore horizontal component = v cos 30= 0.866v

vertical component = v sin 30= 0.866v

The ball travels a distance of 15 m

Therefore distance travelled ...
