Academics

A ball on a string is being whirled in a horizontal circle at constant speed. The circle has a radius of 30 centimeter. The ball completes one revolution every 0.84 s.

Find what angle does the string make with the vertical?

Find the acceleration of the ball?

Find the tension in the string?

Find the angular momentum per unit mass of the ball?

If the string is shortened so that the new radius of orbit of the ball is 15 centimeter (R/2), find at what angle from the vertical will be ball revolve?

Find the angular momentum of the ball if it weighs 5 Newton's?
