Homework Statement
The coefficient of friction between a racecar’s wheels and the track is 1.0. The car starts from rest and accelerates at a constant rate for 400 m. Find the velocity at the end of the race.
so Vo=0m/s
x=400m
mu=1
acceleration is constant
and we need to find Vf
Homework Equations
Ff = muN
Velocity and acceleration:
v=dx/dt
a=dv/dt
Constant acceleration:
v = v0 +at
x = x0 +v0t + 1/2at^2
v^2 = vo^2 + 2ax
The Attempt at a Solution
Personally, I don't know how to approach this. If the mass, acceleration, or time were given I would be able to do this, but since they are not, I'm thoroughly stumped.
