A car of mass 900kg can produce a maximum power of 45 kw. The car experiences a constant resistance to motion of magnitude 1800N.
a) Calculate the maximum speed of the car when travelling on a horizontal road.
b) The car travels up a slope inclined at an angle of 4º to the horizontal. Assuming maximum power is employed, calculate, correct to two decimal places, the acceleration of the car at the instant when its speed is 15m/s
c) The car travels a distance of 800m. Calculate the work done against resistance.
Ok for part a i guess i should do something with the equation Power = force * velocity ???
not sure how to do parts b and c
