Solution Summary

An easy to understand solution is provided with all mathematical steps.

Solution Preview

The car can do work at the rate of 240*746 Joules/sec. If it is doing work at this rate, the time taken by it to cover a distance of (1/10) mile can be found.
(1/10)miles = 0.1 * 1.6 km = 160meters....(1)

HP = 240*746 = 179040 J/s = 179040 Newton meter/sec ---(2)

Newton meter is the work done = Force*distance = m*a*160

(we have S = 0+1/2 a t^2 ==> a = 2s/t^2)

acceleration ...
