Simple harmonic motion/springs question?
A particle of mass 2 kg lies on a smooth horizontal table attached to one end of a light elastic spring whose other end is fixed to a point A on the table. The particle is at rest at E with the spring just taut when it is suddenly given a velocity of 4m/s towards A. The particle comes to instantaneous rest at a point B where AB = 0.8m. If the natural length of the spring is 1m, find its modulus of elasticity. Prove that the particle performs SHM. Find the time taken to travel from E to B.
Thanks!
