Question
Batman (mass = 88.6 kg) jumps straight down from a bridge into a boat (mass = 484 kg) in which a criminal is fleeing. The velocity of the boat is initially +8.25 m/s. What is the velocity of the boat after Batman lands in it?

Answer:
The velocity of the boat after Batman lands in it is 6.97 m/s.
Explanation:
Given that,
Mass of batman, m = 88.6 kg
Mass of boat, m’ = 484 kg
The velocity of the boat is initially +8.25 m/s, v’ = 8.25 m/s
We need to find the velocity of the boat after Batman lands in it. In this case, the conservation of linear momentum works. So,
Initial momentum = final momentum
v = 0 (as the batman was at rest initially)
So, the velocity of the boat after Batman lands in it is 6.97 m/s.
