Question

The motion of particle of mass (m) is described by y =ut +1/2 gt^2(square).find the force acting on the particle

Answer 1

 The equation only shows an acceleration of " g ". 
The value of " g " is the acceleration on an object caused by earth's gravitational pull. 
g = 9.81 meters per second per second. 
The Force is Mass times Acceleration. 
Force on that particle is mg
