A block rests on a rough floor. A horizontal force which increases linearly with time (t),

Question 1

A block rests on a rough floor. A horizontal force which increases linearly with time (t), begins to act on the block at t = 0. Its velocity (v) is plotted against t. Which of the given graphs is correct?

Question 2

Correct Answer is: (d)

The block will begin to move only when the external force becomes equal to the limiting friction at the floor, i.e., at t > 0. Also, as the external force is variable, its acceleration will be variable. The plot of v against t will be a curve.
