The motion of a particle of mass m is described by h= ut + 1//2 "gt"^2 . Find the force acting on particle.

The motion of a particle of mass m is described by h= ut + 1//2 "gt"^2

1.	The motion of a particle of mass m is described by h= ut + 1//2 "gt"^2 . Find the force acting on particle.
Answer» Solution :`H =ut = 1/2 "GT"^2` find a by DIFFERENTIATING h TWICE w.r.t AsF =ma so F = mg
