Impulse and Momentum change

  1. Oct 12, 2006 #1
    A 300 g ball with a speed v of 6.0 m/s strikes a wall at an angle of 30 degrees, and then rebounds with the same speed and angle. It is in contact with the wall for 10 ms.
    (a) What is the impulse on the ball from the wall?
    (b) What is the average force on the wall from the wall?

    What formulas would be used here?

    You know that [tex]F = \frac{d}{dt}mv[/tex]. Since there is change in the horizontal component of velocity, you can calulate the force.
