Given that the car produced work (W) of 32000 kJ during the trip to move forward on a flat pavement with coefficient of friction of 0.2, how far did the car travel?
Assume that the car was at rest then it accelerates to 100 km/h in 12 s, and then which maintained constant velocity of 100 km/h till gas (work) ran out. The mass of the car is 432.5 kg, and ignore the mass change from consuming gas.
F = ma
The Attempt at a Solution
I just did this:
W = (ma - umg)d
To find the distance, is this correct?
