Rate of change in geometry

According to Newton's law of motion,the force depends on the rate of change of momentum. The motion of particle of mass m is described by y=ut+ 1/2 (g t^2) Find the force acting on the particle.

An object is undergoing a non-accelerated motion. Its rate of change of momentum is
