The position of a car that is being slowed at a uniform rate is given by:
s(t) = 25t - 5.25t^2
where s is the displacement of the car from the point at which braking began and t is the
time in seconds after braking began. Find the velocity function for the car, including
its domain.
The answer is v(t) = 25 -11t 0 < or equal to t < or equal to 25/11
I assume I need to find the value of t first, then take a derivative, but I'm not sure
how to get t by itself
0 = 25t - 5.25t^2
5.25t^2 = 25t
and then I don't know what to do.
