Physics 211 11/20 Class Handout Fall 2002 Simple Harmonic Motion 1) A 0.4kg mass is attached to a horizontal spring. The mass is then given a whack with a hammer to the left. The hammer applies a force of 500N but lasts for only 0.01s. The surface is frictionless. The spring constant is k = 1,000N/m. a) What is the period of the motion? Show your work. b) What is the amplitude of the motion? Show your work. You will need to use momentum,

Show your work including buckets. d) What is the maximum acceleration? Show your work including a FBD. e) What is the velocity of the mass when it is 5cm (0.05m) either side of equilibrium? Show your work including buckets. F = 1000N ∆ t = 0.01s...
