A particle moves along the x-axis while acted by a conservative force described

Question

A particle moves along the x-axis while acted by a conservative force described by the potential energy function as shown in the figure. The particle is released from rest at point A. What is the direction of the force on the particle at point A? At point B and at point C? At what value of x does the particle have most kinetic energy? What is the largest value of x reached by the particle during its motion? What are the positions corresponding to points of stable equilibrium? Of unstable equilibrium?

Explanation / Answer

a)upwards

b)downwards , zero

c)at B , as PE is least so KE will be maximum

d) x= 2.25

e) a & b

f) c
