a man exerts 3000.00N of force to push a car 35.00 meters in 90.00 seconds.... 1. what is the work done 2.what is the power generated



Answer :

1).  Work = (force) x (distance)

Work = (3,000 newtons) x (35 meters) = 105,000 newton-meters = 105,000 joules

2).  Power = (work) / (time)

Power = (105,000 joules) / (90 seconds)
                                         = 1,166-2/3 joules per second = 1,166 and 2/3 watts .

Note:
That's no ordinary man.
1,166 watts is the same as roughly 1.6 horsepower.
Not too many people can sustain 1 horsepower or more for 90 seconds.
