Question

A block of unknown mass is at rest on a rough, horizontal surface. A horizontal force $F$ is applied to the block. The acceleration-force graph for the block is a straight line passing through $(2, 0)$ and $(12, 4)$ . The mass of the block is:

Options:

Answer:

A

Solution:

Slope =
$\frac{4}{12 - 2} = 0.4 = \frac{1}{m}$
so
$m = 2.5 kg .$
Option A.
