Question

Mass -spring system is placed inside a car which is moving with acceleration 'a'. What will be time period of oscillation of mass for small displacement?

Answer 1

Solution

When observing the motion of spring

wrt to car, there will be

three forces acting one is pseudo force

and other are gravitational and spring

force. Since pseudo force and

gravitational forces are constant, there

will be no contribution of them on

SHM of the system. So, $T=2n\sqrt{\frac{m}{K}}$,

K is the spring constant
