An 18 kg sled starts up a 31 degree incline with a speed of 3.2 m/s. The coefficient of friction is 0.25.
a.) How far up the incline does the sled travel?
b.) What condition must you put on the coefficient of static friction if the sled is not to get stuck at the point determined in part a?
c.) If the sled slides back down, what is its speed when it returns to its starting point?
