Question

A block of mass 200 kg is kept on a rough horizontal surface. it just begins to move when a force of 100 kg wt. is applied. calculate the coefficient of static friction

Answer 1

Mass = 200 kg.

Force = 100 N.

Coefficient of static friction = ( ? )

It means we need to calculate how much resistance to friction the block is on the rough surface.

So Friction = Coefficient of static friction × Mass × Gravitational Acceleration

100 = 200 × 10 × coefficient of static friction

100 / 2000 = Coefficient of static friction

Coefficient of static friction = 0.05 .

Hope it helps!

Answer 2

Answer:

Explanation:

Total Mass is equal to 200kg.

Force is equal to kg wt.

Coefficient of force is equal to

Force / Mass

100/200

=0.5
