Question

The motion of particle of mass m is given by y= ut+ 1/2 gt^2 the force acting on the particle is

Answer 1

Explanation:

y = 1/2gt² + ut {position of particle wrst time}

dy/dt = gt + u {velocity of particle wrst time}

d²y/dt² = g {acceleration of particle wrst time}

F = ma = mg {where a = g} ANS
