A car, starting from rest, accelerates in the positive x direction. It has a mass of 1.10 x 103 kg and maintains an acceleration of 4.6 m/s^2 for 5 s. Assume that a single horizontal force accelerates the vehicle. Determine the power generated by this force.

Answer 1

F = M*a = 1100 * 4.6 = 5060 N.

d = 0.5a*t^2 = 0.5*4.6*5^2 = 57.5 m.

P = F*d/t = 5060 * 57.5/5 = 58,190 J./s
= 58,190 W.
