a car accelerates from rest at a constant rate x for some time after which it decelaretes at a constant rate y to come to rest .if the total time elapsed is t the total distance travlled by the car is given by what ?

Answer 1

After t1 seconds,

v = x*t1
s = x/2 t1^2

after t-t1 more seconds,

s = (x*t1)(t-t1) - y/2 (t-t1)^2
