A spring, of negligible mass and which obeys Hooke's Law, supports a mass M on an incline which has negligible friction. The figure below shows the system with mass M in its equilibrium position. The spring is attached to a fixed support at P. The spring in its relaxed state is also illustrated.
Mass M has a value of 245 g. Calculate k, the spring constant.
The mass oscillates when given a small displacement from its equilibrium position along the incline. Calculate the period of oscillation.
