A particle of mass 3 kg is attached to end of a light elastic spring of natural length 0.5 m and modulus of elasticity 41 N. The spring rests on a smooth horizontal plane with end fixed. The particle is held at rest and then released. Find the initial acceleration of the particle if initially. Take .
Determine the elastic potential energy stored in an elastic spring of natural length 5 m and a modulus of elasticity 13.4 N, which was compressed to a length of 4 m.
A bowl of mass hangs in equilibrium from the ceiling by a light elastic spring of natural length 0.8 m and modulus of elasticity 7 N. Taking , find the distance the bowl moves when a mass of 1 kg is gently placed in it.
