A boat of mass 40 kg is at rest

A boat of mass 40kg is at rest. A dog of mass 4 kg moves in the boat with velocity 10m/s what is the velocity of the boat(nearly)
Answered by admin @
Answer:
Explanation:
=> It is given that,
Mass of boat, M₁ = 40 kg
Mass of Dog, M₂ = 4 kg
Velocity of dog, V₂ = 10 m/s
Velocity of boat, V₁= x
=> As per the law of conservation of linear momentum, momentum of boat is equal to the momentum of dog. Thus,
M₁V₁=M₂V₂
40 * V₁ = 4 * 10
V1 = 4 * 10 / 40
= 40 / 40
= 1 m/s
Thus, the velocity of the boat is 1 m/s.
