A car of weight 2270 N operating at a rate of 126 kW develops a maximum speed of 39 m/s
on a level, horizontal road.
Assuming that the resistive force (due to
friction and air resistance) remains constant,
what is the car's maximum speed on an incline
of 1 in 20; i.e., if 0 is the angle of the incline with the horizontal, sin theta= 1/20
Answer in units of m/s.
