Answer : When a man jumps out from a boat, he pushes the boat with his feet (action) and the boat also exert an equal force on him in opposite direction reaction. As a result, the man jumps to the bank and the boat moves in the backward direction.

Answer:

0.36

Explanation:

The maximum force of friction exerted by the surface is given by:

$F_f = \mu N$ (1)

where

$\mu$ is the coefficient of friction

N is the normal reaction

The shed's weight is 2200 N. Since there is no motion along the vertical direction, the normal reaction is equal and opposite to the weight, so

N = 2200 N

The horizontal force that is pushing the shed is

F = 800 N

In order for it to keep moving, the force of friction (which acts horizontally in the opposite direction) must be not greater than this value. So the maximum force of friction must be

$F_f = 800 N$
