Power of car along a circular arc#

A car is travelling up a smooth semi-circular slope with a constant speed of \({{ params_v }}\ \rm{km/h}\).


Question Text#

What is the additional power which has to be developed in the engine to keep the car moving at this speed at \(\alpha = {{ params_a }}^{\circ}\) mark?
Neglect air resistance. Treat the car as a particle with mass \(M= {{ params_m }}\ \rm{kg}\)

Answer Section#

Please enter in a numeric value in W.

Part 2#

At what point along the circular arc is the power developed by the engine the maximum if the speed is kept constant?


Answer Section#

  • \( m{A}\)

  • \( m{B}\)

  • \( m{C}\)
