Answer:
a)
b)
c)
d)
Explanation:
Given:
mass of the player,
mass of the ball,
initial velocity of the player,
initial velocity of the ball,
a)
<u>Case:</u> When the player and the ball are moving in the same direction.
where:
total mass after the player catches the ball
v = final velocity of the system
b)
Initial kinetic energy of the system:
Final kinetic energy of the system:
∴Change in kinetic energy
c)
<u>Case:</u> When the player and the ball are moving in the opposite direction.
d)
Final kinetic energy in this case:
∴Change in kinetic energy:
