Question

Example 5.3 The motion of a particle of
mass mis described by y= ut+ - gt. 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
