Question

1. A block weighs 15 N and is suspended from a spring that is attached to the ceiling. The spring stretches by 0.075 m from its unstrained length. By how much does the spring stretch when a 29-N block is suspended from it?

x =Number ____ Units ____

mrad/sNradrad/s^2m/sNo unitss

2. An object in simple harmonic motion has an amplitude of 0.216 m and an oscillation period of 0.620 s. Determine the maximum speed of the motion.

v_max = ____

m/sm/s^2rad/srad/s^2

3. A 0.20-kg object is attached to the end of an ideal horizontal spring that has a spring constant of 120 N/m. The simple harmonic motion that occurs has a maximum speed of 0.83 m/s. Determine the amplitude A of the motion.

A =  _____

mrad/sm/srad
