Question

A boat of mass 60 kg is at the rest.A dog of mass 6 kg in the boat with a velocity of 15m/s.what is the velocity of boat (nearly)?​

Answer 1

Answer:-

By conservation of linear momentum

Momentum of boat = Momentum of dog

m1v1 = m2v2

v1 =?,

m2=4kg,

v2 =10m/s

40v1 =4×10

v1 = 40

4×10=1m/s

Answer 2

Answer:

v1 = 1.5m/s
