What is the magnitude of the impulse imparted by a kicked ball to the foot?

[blayman5]

Homework Statement

A ball of mass 0.4 kg is initially at rest on the
ground. It is kicked and leaves the kicker’s
foot with a speed of 5.0 m/s in a direction 60◦
above the horizontal.
The magnitude of the impulse k~Ik imparted
by the ball to the foot is most nearly

The Attempt at a Solution

I=change(p)
pf-pi
mvf-mvi
(0.4)(5cos60)-(0.4)(0)
=1 N*s
Where did I go wrong in the problem?

WOW how weird we posted the same problem near the same time as each other

Do you go to Bellaire by any chance?

(BTW check my topic, I'm not sure I'm right but I did it differently than you)

Ha, that's really weird. No, I go to Connally. I don't know if the angle would matter or if it just would be the velocity itself. I got it wrong when I did it.

 

[Elbobo]

Ok, I was right, just ignore the angle :D

Ok, thanks!
