A block of mass 1.20 kg is attached to a horizontal spring that has force constant k = 300 N/m. The block moves on a horizontal frictionless surface. The maximum speed of the block during its motion is 5 m/s. What is the amplitude A of the simple harmonic motion of the block?
Homework Answers
The maximum speed of the block is
v_max = wA
A = v_max / k^2 m = ( 5 m/s) ^2/(300 N/m)^2( 1.20 kg) = 2.31 * 10 ^-4 m

2.0 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 590 N/m. The block is pulled from its equilibrium position at x = 0 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along a horizontal x-axis. What is the period (in s) of the resulting motion?
