Question
The motion of a particle of mass 50gm is given by x = 10t + 100t2. Find the force acting on the particle.
Solution
Given,
Mass of the particle, m = 50 gm
The equation of motion of particle is,
x = 10t + 100t2
Therefore acceleration of the particle is,
Mass of the particle, m = 50 gm
The equation of motion of particle is,
x = 10t + 100t2
Therefore acceleration of the particle is,

The force acting on the particle is,
F = ma = 0.05 x 200 = 10 N
F = ma = 0.05 x 200 = 10 N
