1.	A car accelerates from rest at a constant rate alphafor some time, after which it decelerates at a constant rate betaand comes to rest. If the total time elapsed is t, then the maximum velocity acquired by the car is
Answer» `((ALPHA^2 + BETA^2)/(alpha beta)) t` `((alpha^2-beta^2)/(alpha beta))t ` `(alpha beta t)/(alpha + beta)` `((alpha + beta)t)/(alpha beta)` ANSWER :C
