(6%) Problem 8: A car m = 2150 kg is traveling at a constant speed of v = 41 m/s. The car experiences a drag force (air resistance) with magnitude Fd = 360 N. P = 33% Part (a) Write an expression for the power the car must produce P; to maintain its speed. a ( ) 7 8 9 HOME a d Fa 45 6 g h * 1 2 3 k m P + 0 END S t V VO BACKSPACE DEL CLEAR S Submit Hint Feedback I give up!

A 33% Part (c) The car encounters an incline which makes an angle of 0 = 7 degrees with respect to the horizontal. The cruise control kicks in and increases the power to maintain the speed of the car. What is the new power (in hp) required to maintain a constant speed?
