Given information
We are given that:-
The coefficient of static friction needed for a drag racer to cover in s, starting from rest.
Step-by-step explanation
Step 1.
Assume that the static frictional force is the only force accelerating the racer. Then consider the free-body diagram for the racer as shown:-
It is apparent that the normal force is equal to the weight, since there is no vertical acceleration. It is also assumed that the static frictional force is at its maximum.
Thus,
The acceleration of the racer with an initial speed of .
