I couldn't get my head around this problem... I'd like some input and some answers to aim towards please... I'm actually a pretty bright student, I just can't figure this out... maybe a blonde day lol?
A baseball of mass 55g leaves the pitchers hand at a speed of 48m/s. THe horizontal distance to the batter is 20m. Assuming that air resistance is negligible, determine the following:
a) the time for the ball to travel the first 10m
b) the time for the ball to travel the second 10m
c) the distance that the ball fell in the first 10m of horizontal travel
d) the vertical velocity of the ball just before it reached the batter.
If the ball missedthe bat and was taken by the catcher, whose glove moved backwards 30cm as he caught the ball, calculate the following:
e) the change in velocity of the ball as it was caught
f) the acceleration of the ball as it was caught
g) the force exerted on the glove by the ball as it was caught
h) the force exerted on the ball by the glove as it was caught
