Question

A boy of mass 60kg jumps out of a moving boat of mass 500kg with a velocity of 5m/s . The velocity with which the boat starts moving backward is -
1. 0.3 m/s
2. 3 m/s
3.2.5 m/s
4.0.6 m/s​

Answer 1

Answer:

The correct option is (4): 0.6 m/s​

Explanation:

As we know that

Force action = Force reaction

60 x 5/t = 500 x VB /t

300 / t = 500 x VB/t

300 = 500 x VB

VB = 300/500

VB = 0.6 m/s

Thus the velocity with which the boat starts moving backward is 0.6 m/s
