Question

A 20 kg block is in motion on a rough horizontal surface A horizontal force of 60N is required to
keep the body moving with constant speed. The coefficient of kinetic friction is (g = 10 ms )
​

Answer 1

Answer:

answer is 196 N this is the right answer

according to newtons 2nd law of motion F=MG

so M =20kg

and G=9.8 so force = 196N
