Q1a sketch a graph showing elastic force exerted by the spring with spring constant k as a function of its displacement from x = a to x = a. Q1b a m = 0. 500 kg glider is attached to an ideal spring with a force constant k = 450 n/m, undergoes simple harmonic motion with an amplitude of 0. 40 m. (a) determine the angular frequency of the motion. [2 points] (b) determine maximum speed and maximum acceleration of the glider. [2 points] (c) determine total mechanical energy of the system.
