Question

Suppose a body is moving with a simple harmonic motion and its velocity at the equilibrium (mean) position, i.e. when x=0m, is:

a) Maximum

b) Cannot be determined

c) Minimum

d) Zero

Answer 1

The correct option is (a)because when object is in mean position net force acting on it is zero.so acceleration of particle is zero .In s.h.m force always act in the opposite direction of velocity so force always decraese the velocity and when force is zero velocity has maximum value.

(b)since question is very specific so cannot be determined is not a option afterall.

(c)velocity in s.h.m is minimum at extreme position and minimum velocity is zero.so this option is not correct

(d) same explanation as given in (c)
