Answer:
u = 5 m/s
Explanation:
given,
Mass of ice skater, M = 45 Kg
initial speed = 0 m/s
mass of the ball, m = 5 Kg
velocity of skater and the ball,V = 0.5 m/s
speed of the ball = ?
using conservation of momentum
m u + M u' =( M + m ) V
initial speed of ice skater is zero
5 x u + 45 x 0 =( 45 + 5 ) V
5 u = 50 x 0.5
5 u = 25
u = 5 m/s
hence, the speed of the ball is equal to 5 m/s
