Thanks again jbriggs444 i read the question again and i realized that i over did.
Since power = work/time
so this is what i did.
372000w= Work/11.5s
(multiply both sides by 11.5s)
Work = 4278000J
Thanks!
Just correct me if I am wrong, question b) should be:
Work = Force*Distance
4278000J =...
Oh boy so sorry jbriggs444 that problem was a typo! I always knew my teacher warned me about being careful.
What i sould had wrote is power = force*distance/time.
And about the constant force i think the question only wanted me to use average force(i think).
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...
Hello guys! This is my introduction to you all, i think.
I am just a student currently interested in physics and at the same time troubled by it, and google brought me here.
Hope we have some fun time together.
