The problem is as follows:
A car is going at initial velocity 1 m/s when a brick wall appears 50 m away. Assuming the driver reacts instantaneously and accelerates at a constant rate of 5 $m/s^2$, at what speed will the driver hit the brick wall?
I tried using the formula of $$d=Vt+1/2at^2$$ and tried to isolate for time with algebraic manipulations but the farthest I get is to $$t=d/(V+1/2at)$$ How to solve for time? With time I can find final velocity using equation Final Velocity = Initial Velocity + Acceleration * Time.
I could not find the answer in any other questions.
