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

A particle of mass 0.3 kg is subjected to a force F = - kx , Where = 15 Nm^(-1) . What will be its initial acceleration when particle is released from a point 20 cm away from origin ?

A particle of mass 1 kg is subjected to a force which varies with distance as shown. If it starts it s journey from rest at x=0. then its velocity at x=15 m is

A particle of mass 0.1 kg is subjected to a force which varies with distance as shown in figure. If it starts its journey from rest at x=0 , its velocity at x=12m is

A particle of mass 0.1 kg is subjected to a force which varies with distance as shown in figure. If it starts its journey from rest at x = 0, its velocity at x=12 m is

A particle of mass m is acted upon by a force F= t^2-kx . Initially , the particle is at rest at the origin. Then
