Question

4.What is the force acting on the
particle if the motion of the particle
is given as y=ut+1/2gt2
*​

Answer 1

Answer:

Gravitational Force

Hope this helps you...

Answer 2

Answer:

The force will be mg

Explanation :

v = ut + 1/2 gt2

Now difference v with respect to t which gives us the velocity as dy / dt = v ,

dv / dt = u + 1/2 g ( 2t )

v = u +gt --------------------- eqn i

Now difference v with respect to t which gives us the velocity as d2y / dt2 = dv / dt = a ,

dv / dt = 0 + g

a = g ------------------------- eqn ii

Now,

We know that the force acting on a mass m is given by F =  ma

Now,

From eqn ii substitute a = g

Hence ,  F = mg .
