Ablock of a certain material begins to slide on an inclined plane when the plane is inclined to an angle of 18.26°.
if a solid cylinder is fashioned from the same material, what will be the maximum angle at which it will roll without slipping on the plane?

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
