A 126.6 kg man is in a stationary 51.6 kg rowboat. The man jumps off the back of the boat with a horizontal velocity of 8.84 m/s. How fast does the boat move after the man jumps?

3,6 m/s

Explanation:

You need to calculate the force with which the man jumps, and since

Force = Mass * Speed, here's what you have:

Force = 8,84 * 51,6

Force = 456,144 N

Then, you would have to apply the same formula, but this time to find the speed of the boat, using the force:

456,144 = x * 126,6

x =~ 3,6 m/s
