Answer 1

Answer:

Hope it helps you ✌️❣️❣️

Explanation:

Because of the conservation of momentum.

Initially, both the boat and the passenger are stationary and have a total mass m1 + m2, where m1 is the mass of the boat and m2 is the mass of the passenger. Since they are stationary, they have zero momentum.

When the passenger steps out, he obtains some velocity v1, and thus have momentum p1= m1 v1. By conservation of momentum, the boat should have momentum of p2= m2 v2.

By conservation of momentum, initial momentum = final momentum.

initial momentum (when both are stationary) = zero

this requires the final momentum to be zero too!

thus, final momentum = p1 + p2 = 0

m1 v1 + m2 v2 = 0

v2 = - (m1/m2) v1

The negative sign indicates that it is moving in the opposite direction of v1
