Physics 53 Quiz #9a Fall 2007 Name ___________________________ Recit. Section _______ Circle the correct answer: [2 points for each part] Consider a mass m attached to a spring with constant k and oscillating on a frictionless horizontal surface. If the displacement of the mass as a function of time t is given by x ( t ) = A cos( ω t + φ ) with A = 4.00 cm, ω = 3 π s -1 , φ = π /2, then 1. the oscillations start at t = 0 at: a) x = ! 4 cm. b) x = ! 2 cm. c) x = + 2 cm. d) x = + 4 cm. e) x = 0 cm. 2. the total distance traveled by the mass in one cycle is:
