1. Two people build precison timing devices, one with a simple pendulum, one with a simple mass-spring. Each is to have a period of 2 s. The Fg = 9.8 m/s^2. Select the appropriate parameters for this to happen. Part B - which device is more precise at the equator? 2. I have no idea :(...

1. A merry go round (1000kg) initially at rest with a diameter of 4m is pushed with a tangential force of 500N for 10s. Find the angular velocity, angular momentum, and rotational kinetic energy. After this, a little girl (mass - 1 kg) is placed on the rim of the merry go round.. Calculate the...
