Homework Statement:
 Calculate the horsepower required to move a 2000 lb. car half a mile in 6 seconds.
Relevant Equations:

1 hp = 550 ft lb / sec
work = distance (ft) * force (lbs)
hp = (distance(ft) * weight(lbs)) / 550(ft lbs/sec)
power = work / time
My attempt at the solution goes as follows:
power = work / time
power = (distance * force) / time
power = (2640 ft * 2000 lb) / 6 seconds = 880000 ft lb / sec
horsepower = 880000 ft lb/sec / 550 ft lb/sec = 1600 hp
however i do not know if this is correct
power = work / time
power = (distance * force) / time
power = (2640 ft * 2000 lb) / 6 seconds = 880000 ft lb / sec
horsepower = 880000 ft lb/sec / 550 ft lb/sec = 1600 hp
however i do not know if this is correct
