17. The motions of a car and a truck along a straight road are represented by the graph, which plots velocity (v) vs. time (t). The two vehicles are initially alongside each other at time t = 0. https://tcan4424-oakcliff-ccl.gradpoint.com/Resour... Assuming the accelerations of the car and truck are constant for 0 < t < 2T, at which value of time (t) will the car once again be alongside the truck?

for the car 

Vc = at

x = 1/2 at^2

for the truck 

Vt = V0 

x = V0*t

1/2 at^2=v0*t

and V0= aT

V0= 1/2 at 

therefore, 

t = 2V0/a = 2T.
