## Homework Statement

Pick a car, find its acceleration. calculate the force necessary to move the car with this acceleration and the minimum coefficient of friction to accomplish this. repeat the calculation of the coefficient of friction on a 20 degree incline.

## Homework Equations

How do i calculate the coefficient of friction? on a 20 degree incline as well?

## The Attempt at a Solution

0-60= 5.8s

weight=1392.7kg

acceleration= change in velocity/ change in time

acceleration= 26.82m/s / 5.8s = 4.62 m/s2

weight= massx acceleration of gravity

1392.7= m(9.81 m/s2)

mass= 141.97

force= mass x acceleration

F= 141.97x 4.62 m/s2

F= 646.49 N

How do i find coefficient of friction and the coefficient of friction on a 20 degree incline?

force= mass x acceleration
