A 0.500 kg stone is moving in a vertical circular path attached to a string that is 75.0 cm long. The stone is moving around the path at a constant frequency of 2.20 rev/sec. At the moment the stone is overhead, the stone is released. The velocity of the stone when it leaves the circular path is   Multiple Choice   10.4 m/s horizontal.   10.4 m/s vertical.   22.0 m/s horizontal.   22.0 m/s vertical.   31.4 m/s horizontal.

3. A simple pendulum is suspended from the ceiling by means of a string of length 1.60 m. Now you start with the pendulum at 16.6 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 55.4 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it?    4.78 m/s    3.50 m/s    3.68 m/s    1.14 m/s

3 1 3 4 5 t (s) What is the particle's acceleration at t = 4.5 s? 1 m/s^2 -1 m/s^2 -2 m/s^2 3 m/s^2 O 2 m/s^2 (s/w) A

A 1.00-kg mass is attached to a spring hanging vertically and hangs at rest in the equilibrium position. The spring constant of the spring is 1.00 N/cm. The mass is pulled downward 2.00 cm and released. What is the speed of the mass when it is 1.00 cm above the point from which it was released?   0.0443 m/s     1.73 m/s     1.67 m/s     0.0201 m/s     The mass will not reach the height specified.
