Suppose a sphere going 10m/s on a horiz. surface is going toward a frictionless ramp(incline of 25 degrees). Would its velocity, as it leaves the top of the ramp, be greater,less than or equal to its velocity if the ramp had friction?
The Attempt at a Solution
I thought that the speed would be less than the vel of the ball rolling up a ramo with friction bc if the ball is slipping up the ramp than there would be less total kin energy( when taking translational and rotational kin energy into account) and that would dec its speed. I dont know if my logic is correct though?
