where x is in meters and t in seconds. Find

Subjective
A car accelerates from rest at a constant rate $\alpha$ for some time after which it decelerates at a constant rate $\beta$ to come to rest. If the total time lapse is t seconds, evaluate.

(i) maximum velocity reached, and

(ii) the total distance travelled.

$(i)\,{{\alpha \beta } \over {\alpha + \beta }}t$

$(ii)\,{1 \over 2}{{\alpha \beta } \over {\alpha + \beta }}{t^2}$
