When a body of unknown mass is attached to an ideal spring with force constant 120 N/m, it is found to vibrate with a frequency of 6.00 Hz. Find (a) the period of the motion; (b) the angular frequency; (c) the mass of the body.

Solution 7E Problem (a) Step 1: Force constant of the spring k = 120.0 N/m Frequency of vibration f = 6.00 Hz Step 2: To find the period of the motion Period of vibration is reciprocal of the frequency T = 1f T = 1 6.00 T = 0.1667 s The period of the motion is 0.1667 s Problem...
