The mass of the man is 63 kilograms
There is it written down properly. Its hard to type this stuff in here
Answer:disequilibrium
Explanation:
When the net force is not zero it is called disequilibrium
In Linear motion the swimmer swims
Answer:
159 N
Explanation:
The force of friction, Fr is a product of coefficient of feiction and the normal force. Therefore, Fr=uN where N is the normal force and u is coefficient of friction. Here, we have two coefficients of friction but since it is sliding, then we use coefficient of kinetic energy. Substituting 0.25 for u and 636 N for N then
Fr=0.25*636=159 N
Therefore, the force of friction is equivalent to 159 N
