Question

A boat of mass 50 ky is at
rest. A dog of mass 5 kg
moves in the boat with a
velocity of 20 m/s. What is
the velocity of boat? (nearly)​

Answer 1

Answer:

hope it will help you ........

Answer 2

By conservation of linear momentum

Momentum of boat = Momentum of dog

M1V1 = m2v2

M1 = 50kg

V1 = ?

m2 = 5kg

V2 = 20m/s

50V1 = 5 × 20

50V1 = 100

V1 = $\frac{100}{50}$

V1 = 2m/s
