A 1210 kg car is driving on 60 km/h on an inclined plane. The car is located on the top of the plane. The plane is 655 m long and the angle is 4.50 degrees.

a) What will the speed of the car be if there is no friction?

b) Now the car is on 85 km/h at the bottom of the inclined plane. How much friction force works on the car its way down?

c) If the same friction force works on the car as when it drown up the plane, what does the mechanical power require to be so the car can drive on 85 km/h ?

d) Let’s assume that the same friction force works on the car that drives in a normal driving. How much gas will the car spend on a hundred ef the heat of reaction of the gas is 38 MJ/litres and the efficiency is 21 %
