Document Summary
Tutorial #3 (weeks of february 10 and 24, 2014) A 0. 450 kg block resting on a frictionless horizontal surface is attached to a spring whose constant force is 45. 0 n/m. The velocity of the mass is v=40 cm/s when the mass is at x= 3 cm (measured from the equilibrium position x=0): find the angular frequency and the amplitude of the motion, determine the phase at that instant. 92. 0: what is the acceleration of the system when the mass is at x= 10 cm? a. 2: what is the total energy stored in the system. 2: find the speed of the mass when it first passes through the equilibrium position. For that to happen the work done by friction has to equal the maximum energy. A simple pendulum has a mass of 0. 250 kg and a length of 1. 50 m. it is displaced through an angle of 15. 0 and then released.
