ai)What total distance s did the block slide?
aii) What is the total vertical height through which the block descended?
b)A small metal ball is suspended from the ceiling by a thread of negligible mass. The ball is then set in motion in a horizontal circle at an angle of 29 degrees from the top, so that the thread describes a cone. The acceleration of gravity is 9.8 m/s2 .
bi) What is the speed of the ball when it is in circular motion in m/s?
bii)How long does it take Tperiod for the ball to rotate once around the axis?
