Question

the motion of a particle of mass m is described by y=ut+1/2at^2.find the force acting on the particle.

Answer 1

force is mass×acceleration
force is m×2y-2ut÷t^2

Answer 2

HLO MATE HERE IS UR ANSWER.

We know that.

y = ut + 1/2 gt^2.

now ,

v = dy/dt = u + gt.

acceleration.

a = dv / dt = g.

Then the force is given by F = ma = mg.
