hi peeps, can u guys help me with this question:
A wheel weighing 40kg is rolling down a hill, inclined at 30 degrees. After reaching a speed of 5m/s, the wheel falls over on its side and begins sliding down the hill.
1. if the coefficient of friction for the sliding wheel is 1.00, independent of the wheel's velocity, how long will it take the wheel to come to a complete halt?
2. if the coefficient of friction is instead 0.500, will the wheel still stop? why or why not?
im having trouble with the thing about the wheel becoming sliding after reaching 5m/s. i would really appreciate some help.
thanx
