Question 30: Laws of Motion

Question

The motion of a particle of mass $m$ is described by $y = ut + g{t^2}$. The force acting on the particle will be

Accepted Answer

Given, $y = ut + g{t^2}$
Comparing with equation of motion $y = ut + {1 \over 2}a{t^2}$
we get, $a = 2g$
$	herefore$ Force $ = m 	imes a = m 	imes 2g = 2mg$
