I have been struggling to understand how to do this question so some guidance would be great.
A racing car of mass 941kg accelerates from 28km/h to 102km/h over a distance of 297m. Frictional forces and wind resistance can be assumed to be 1160N.
Determine the following:
a) The average acceleration
b) The time taken to accelerate from 28km/h to 102km/h
c)The tractive force produced by the car to provide this acceleration
d)The car finally reaches a speed of 212km/h. Friction and wind resistance are 2761 at this speed. What power output is required to maintain this speed?
I have been playing around with equations and numbers and have just got myself really confused now, any help would be greatly appreciated.
