A spring is mounted over an air track in such a way that the one end of the spring is fixed and the other is connected to a spring scale. When the spring is stretched to 0.01 m a force of 1 N is registered on the spring scale. The spring is relaxed and a glider of 0.43 kg (resting on the air track) is connected to it. The glider-spring system is then pulled to the right through a distance of 0.01 m. Calculate the following:

(a) The spring constant k. (1 mark)

(b) The period of motion. (1 mark)

(d) Calculate the amplitude and phase angle of the spring-glider system, if the initial velocity and position of the glider is 0.3 m/s and 0.72 m, respectively.

(e) Utilize all the information already calculated and set up equations for the displacement, velocity and acceleration as function of time.

A spring of spring constant k sits on a frictionless horizontal surface, one end of the spring is attached to a wall, the other end to a block of mass M, also resting on the frictionless surface. The system executes simple harmonic motion such that at a given point the mass is -1/6 of the amplitude moving away from equilibrium, and 0.5 seconds later it has 1/7 of the maximum speeds, moving towards equilibrium, having passed equilibrium once. 1) How...
