Homework Statement
A 500hp Mustang is able to push this 1750kg car down a 410m drag strip in a time of 11.5s.
a) What is the work done by the car?
b) What is the average force during the car's motion.
Given: Power = 500hp = 372000w
Mass = 1750kg
Distance = 410m
Time = 11.5s
Homework Equations
Work = Force*Distance
Power = Work/Time
The Attempt at a Solution
Power = Force*Distance
372000w = (Force*410m)/11.5s
372000w = (410x N/m)/11.5s
Multiply each side by 11.5s
427800w = 410x N/m
Now i eliminated time, work should be 427800N, but that does not look correct. Need help and explanation here.
P.s. There will be no problems solving question b since if i get the work done I can divide it by the time.
Thanks in advance,
