How high does the ball rise on the frictionless side

[From: ] [author: ] [Date: 12-06-26] [Hit: ]
How high does the ball rise on the frictionless side?Please help me!-w = v/r = (1/r)√[2gh/(1+k)] where k = 0.4 for a solid sphere.w = 86.4 rad/sec; v = 3.......
If the ball is released from rest at a height of 0.77 m above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? Assume the ball is a solid sphere of radius 3.8 cm and mass 0.14 kg.

How high does the ball rise on the frictionless side? Please help me!

w = v/r = (1/r)√[2gh/(1+k)] where k = 0.4 for a solid sphere.

w = 86.4 rad/sec; v = 3.283 m/s

H = v²/2g = 0.55 m


Note that mass does not matter.....
