Answer the following questions :

A. Using a horizontal force of 200 N, we are moving a wooden cabinet across a floor at a constant velocity. What is the friction force that is being exerted on the cabinet?

B. Ram's bike is moving with a speed of 90 km/hr. In traffic he had to reduce his speed to 30 Km/hr. By how much will the force of friction change? [3 MARKS]

Solution

Part A : 1.5 Marks
Part B : 1.5 Marks

A. The cabinet will move with constant velocity only when the net force on it is zero. Therefore, force of friction on the cabinet = 200 N, in a direction opposite to the direction of motion of the cabinet.

B. Friction force will not change as the friction force doesn’t depend upon the velocity of the body.
