Hi All,
I've been asked to re-work the below as my original method was incorrect.
Below is my second attempt on the question, which I would appreciate some input from someone a more knowledgeable than myself.
Thanks,
1. Homework Statement
A racing car of mass 850 kg accelerates from 20 km/h to 160 km/h over a distance of 300 metres. Frictional forces and wind resistance can be assumed to be 800N.
Determine the following:
(iii)The tractive force produced by the car to provide this acceleration
F=MA
44.442=5.5622a300
a=3.24 m/s2
Force = 3.24 * 850 = 2754 joules
Tractive Force = Force + Frictional Forces
3554 = 2754 + 800
