In the figure, a block weighing 17.1 N, which can slide without friction on an incline at angle theta = 30.0°, is connected to the top of the incline by a massless spring of unstretched length 0.310 m and spring constant 110 N/m. The block is initially at its equilibrium position. (a) How far from the top of the incline is the block’s equilibrium point? (b) If the block is pulled slightly down the incline and released, what is the period of the resulting oscillations?
