Answer:
48 m/s
Explanation:
From the Law of Conservation of Linear Momentum,
initial momentum (p1) = final momentum (p2)
⇒ 5(v) + 75(0) = (5+75) × 3
(since, after the collision, both man and ball move with the same common velocity of 3 m/s)
⇒ 5v + 0 = 80 × 3 = 240
∴ v = 240/5 = 48
Hence, the ball should move with a velocity of 48 m/s
Hope this answer helps you....
