Pop Quiz! How fast does the baseball travel...?
Pop Quiz! Time for some easy points: solve the problem. The first dated correct answer will be chosen as best when allowed.
Suppose that a baseball player throws a baseball straight up in the air and then hits it as it is coming down. Assume that it gets hit with a horizontal impulse of
[15.6 0] (towards the positive direction of the x-axis)
and that the mass of the baseball is 0.14 kg. How fast does the baseball travel when it leaves the bat?
Note: Since the impulse is along the x-axis, we can ignore the y-axis velocity of the ball. Its initial x-axis velocity is 0. (Points: 5)
