Select the higher harmonics of a string fixed at both ends that has a fundamental frequency of 80 Hz.

In a spring gun, a spring of mass 0.240 kg and force constant 3100 N/m is compressed 2.00 cm from its unstretched length. When the trigger is pulled, the spring pushes horizontally on a 5.5*10-2 kg ball. The work done by friction is negligible.

If two forces 3N and 20N acts on a body of mass 15kg, find the acceleration
