Homework Statement
Recent studies have raised concern about `heading' in youth soccer (i.e., hitting the ball with the head). A soccer player `heads' a size 4 ball, deflecting it by 38.0 deg, but keeping its speed of 19.60 m/s constant. A size 4 ball has a mass of approximately 0.302 kg. What is the magnitude of the impulse which the player imparts to the ball?
CORRECT ANSWER: 3.85 kg*m/s
Homework Equations
p=mv
draw a vector diagram
The Attempt at a Solution
I drew a vector diagram with the vector p=mv=5.9 going in the +x direction. I then drew the deflection of 38 degrees going in the negative and positive direction.
Ok so I found the hypotenuse (the redirection) to be 7.48.
Then I thought it would be 7.48-5.9, but alas, nope.
Any help?
