can you help?

A ball is released from a height h so that, when it rolls down the track, it enters a loop of radius 5.00 m. The height h is high enough so that the ball can complete the loop without falling. Point X is the highest point in the loop. The loop is a perfect circle. side view of loop ball X h loop Ignore the effects of friction. a) What is the minimum speed that the ball needs to have at Point X if it is not to lose contact with the track? [2 marks] b) What is the minimum height from which the ball can be released if it is to complete the
