Q1. A solid disk of radius 6.00 and mass 1.75 that is rolling at a speed of 2.10 begins rolling without slipping up a 10.00 slope.

Q2. A civil engineer wishes to plan a curved exit ramp for a highway in a way that a car will not have to rely on friction to round the curve without skidding. In the other words, a car moving at the designated speed can negotiate the curve even while the road is covered with ice. Such a ramp is usually banked; this means the roadway is tilted toward the inside of curve. Suppose the designated speed for the ramp is to be 13.40 m/s (30.00 mi/h) and the radius of the curve is 50.00 m. At what angle should the curve be banked?
