Please help Brainliest for best answer! A long rope with a heavy ball tied to its end is attached to the ceiling. The ball-pendulum is pulled back 10 degrees from vertical and released. When the ball reaches its lowest point it has a speed of 2.0 m/s. Determine the length of the rope and the period of oscillation for this ball-pendulum system? For an extra challenge choose another angle (less than 15 degrees) and show that the period remains the same even though the height h and velocity v differ.
