A rocket is accelerating upward at 4.90m/s2 from the launchpad on the earth. Inside a small 1.50-kg ball hangs from the ceiling by a light 1.10-m wire.
A) If the ball is displaced 8.50 ? from the vertical and released, find the amplitude of the resulting swings of this pendulum.
B) If the ball is displaced 8.50 ? from the vertical and released, find the period of the resulting swings of this pendulum.
