Q. An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor will the amplitude of oscillation decrease after 10 cycles?

Q. A mass of 10 kg has 3 forces exerted against it, as shown in the diagram below. Given the information below, calculate the magnitude and orientation of the resultant force.

F1 has a magnitude of 10.5 N, with θ = 15° to the horizontal

F2 has a magnitude of 55.0 N, with θ = 33° to the vertical

F3 has a magnitude of 23.9 N, with θ = 45° to the horizontal
