Question

a block of mass 2kg is on a horizontal surface begin to move when it is pulled at 30degree witj the horizontal by 10n force.find the coefficient of limiting friction​

Answer 1

Answer:

The maximum static friction, f

s,max

=μ

s

N=0.5×2kg×10ms

−2

or, f

s,max

=10N>2.5N, which is greater than the applied horizontal force.

Hence, friction can impede the motion and the necessary required frictional force to balance the horizontal applied force will be equal.

Therefore, f=2.5N.
