a)Determine the total energy of the ball, using the floor as the zero point for gravitational potential energy.

b)Determine the speed of the ball at point P, the lowest point of the circle

c)Determine the tension of the thread at...

i. the top of the circle

ii. the bottom of the circle

The ball only reaches the top of the circle once before the thread breaks when the bal is at the lowest point of the circle.

d)Determine the horizontal distance that the ball travels before hitting the floor

I'm not sure where to begin.

If anyone can help me it would be great!!
