1 A car of mass 800 kg moves in a straight line along a horizontal road.
There is a constant resistance to the motion of the car of magnitude 600 N .
When the car is travelling at a speed of \(15 \mathrm {~m} \mathrm {~s} ^ { - 1 }\) the power developed by the car is 27 kW .
Determine the acceleration of the car when it is travelling at \(15 \mathrm {~ms} ^ { - 1 }\).
