A vibrating string has a fundamental frequency of 224 Hz. The tension is then increased by a factor of2.4. What is the new value of the fundamental frequency?Hz
A golf ball traveling 3 m/s to the right has a head-on with astationary bowling ball in a friction-free environment. If the collision is almost perfectly elastic, the speed of the golf ball immediately after the collision is:
A mass hangs on the end of a massless rope. The pendulum is held horizontal and released from rest. When the mass reaches the bottom of its path it is moving at a speed v = 2.4 m/s and the tension in the rope is T = 15.1 N.
