A ball on the end of a string is whirled around in a horizontal circle of radius 0.340 m. The plane of the circle is 1.20 m above the ground. The string breaks and the ball lands 2.50 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. Magnitude m/s Direction

17. What will happen if to a ball on a string if the string brea what speed? l happen if to a ball on a string if the string breaks? What direction will it move, and al erseus want to attack a cyclops with a rock and sling. He uses a.8-kg rock to a string so that he can swing it in a circle above his head. The strine is 75 meters long and while swinging, the rock makes revolutions...

9) A ball of mass m is attached to the ceiling via a string of length L. The ball is given a push to set it in motion. The ball then travels in a horizontal circle, such that the string makes and angle 0 with the vertical. It is observed that it takes time T for the ball to make one complete revolution. How can this experiment be used to measure the magnitude of the gravitational acceleration g. problem 9...
