 A truck mass of m=1210kg drives up an incline at a constant speed of v = 12.7 m/s. The forces of air drag and friction combine to give a non-conservative force opposing the motion of f=515N. The truck's motor has power P=65.7kW with efficiency e=0.81so that a fraction 1-0.81 of the power goes into heat and noise.

a)Enter an expression for sin(φ), where φ is the maximum slope for which the truck can maintain a constant speed. Use g for the acceleration due to gravity. 

b)What is φ in degrees?
