A force of 98N is able to just move a body of mass 28kg on a rough horizontal surface. Calculate the coefficient of static friction.

Answer»

ANSWER:

COEFFICIENT = 10/28

Explanation:

N=Mg= 28x9.8

f= coefficient X normal

f= coefficient x 28X 9.8

also, f=98N

98= coefficient x 28 x 9.8

980/98= coefficient x 28

10/28= coefficient
