A particle of mass 0.3 kg is subjected to a force of F = -kx with k = 15N/m. What will be the initial acceleration if it is released from a point 20 cm away from the origin?

Answer by:- Diptey

mass of the particle, m = 0.3 kg
applied force, F = - kx;
k = 15 N/m
x = 20 cm = 0.2 m
Let the acceleration of the particle = a
Using the Newton’s 2nd law of motion we get,
F = m* a or, -kx = ma
or, - 15 * 0.2 = 0.3 * a or, a = -3.0/0.3
or, a = -10m/s^2
