A 12-lb block moves from the conveyor belt to a table by travelling around a smooth, semicircular track of 10-ft radius. (a) Determine the speed required on the conveyor to ensure that the block stays on the semicircular track and makes it to the table. (b) Determine the distance that the block moves along the length of the table. The coefficient of kinetic friction between the block and the table is 0.2.

A 5.2 kg ball is rolling at a speed of 6.3 m/s when it encounters a ramp. How high can it roll up the ramp before coming to astop? (put your answer with 3 decimal places!) m

Please provide complete solution for verification. Thank you!
