A motorcycle ( mass of cycle plus rider = 2.50 xx 10^(2) kg ) is travelling at a steady speed of 20.0 m/s. The force of air resistance acting on the cycle and rider is 2.00 xx10^(2) N. Find the power necessary to sustain this speed if the road is sloped upward at 3.70^(@) with respect to the horizontal .
