Homework Answers
A)
Time period, T = 0.5 sec
B)
Frequency, f = 1/0.5 = 2 Hz
C)
Angular frequency, w = 2 pi f = 2 pi x 2 = 12.57 rad/sec
D)
Spring constant, k = mw^2 = 0.5 x 12.57^2 = 78.96 N/m
E)
Maximum speed, v = Aw = 0.35 x 12.57 = 4.4 m/s
F)
Force, F = kA = 78.96 x 0.35 = 27.64 N

Problem 1 A block of mass m is sliding on a frictionless, horizontal surface, with a velocity vi . It hits an ideal spring, of spring constant k, which is attached to the wall. The spring compresses until the block momentarily stops, and then starts expanding again, so the block ultimately bounces off (see Example 5.6.2). (a) Write down an equation of motion (a function x(t)) for the block, which is valid for as long as it is in contact...
