A solid disk of radius .20 meters is rolling without slipping with a velocity of 3.7 m/s as it reaches the base of a 10o ramp as shown.

a) How high does the center of the wheel go?

b) Determine the total time spent on the ramp (that is, going up and rolling back down).

(no diagram or additional information was presented to me. this was all the information that was given)
