Question 63: Laws of Motion

Question

A wooden block, initially at rest on the ground, is pushed by a force which increases linearly with time $$t$$. Which of the following curve best describes acceleration of the block with time :

Accepted Answer

Acceleration (a) $$=\frac{f-F}{m}$$
When applied force became equal to $$f_{\max }$$, block will start moving.
As $$F$$ increases linearly, so acceleration of also moving block will increase linearly.
