Physics quadratic eq help ASAP! Fast 10 pts!?
Given: V = 25 m/s
a = -0.4 m/s^2
So S=displacement, V=initial velocity, t=time, a=acceleration
S = V t + 1/2 a t^2
235 = 25 t + 1/2 (-0.4) t^2
235 = 25 t -0.2 t^2
Solve for t using quadratic equation:
t = 10.25 sec
So you see, I dont know how to use quadratic and how it arrived at 10.25 sec. So please show me how with steps, thanks!
