A force of 3 N stretches a spring by 1 m. (a) Find the spring constant k.
(b) A mass of 4 kg is attached to the spring. At t-0, the mass is pulled down a distance 1 m from equilibrium and released with a downward velocity of 0.5 m/s. Assuming that damping is negligible, determine an expression for the position y of the mass at time t. (Assume that y is the distance in meters from the equilibrium position, where distances are measured positive in the downward direction. Enter your answer as an equation involving y andt.) V 3
