Question

4) A basketball player (P1) catches a pass from her teammate (P2) and immediately passes the ball back to her in one continuous motion. At the instant P1 catches it, the 0.7 kg basketball is travelling horizontally towards her at 6 m/s. The ball leaves her hands 0.2 s later, travelling horizontally away from her at 7.5 m/s. Assume P1 applied a constant horizontal force to the ball throughout the time it was in her hands

What are the magnitude and direction (towards or away from P1) of the horizontal linear impulse that P1 applied to the ball while it was in her hands? (4 points)

What are the magnitude and direction (towards or away from P1) of the constant horizontal force that the player applied to the ball while it was in her hands? (Use your answer from part a to answer) (4 points)

Explanation / Answer

A) Apply, Impulse = chnage in momentum

= m*(v2 - v1)

= 0.7*(7.5 - (-6))

= 9.45 N.s

direction : Away from P1

B) Impulse = F*t

==> F = Impulse/t

= 9.45/0.2

= 47.25 N

direction : Away from P1
