    Where and when does the car catch the truck?

    ok so i corrected the velocity of the truck it gives me this 0 (t) + (1/2) (2.7) (t)^2 = 4 ( t) + (1/2) (1) (t)^2 + 8 and then it gives me an equation like this 0= 0.85t^2- 4t-8 and the anwser is 6.2192121 but its still nor correct :s and sorru about the other thread :p

    Where and when does the car catch the truck?

    i have tried s=ut + (1/2)at^2 In 4 seconds, truck travels a distance of 0 (4) + (1/2) (1) (4)^2 = 0 + 8 = 8 now, when car starts, truck is already 8 m ahead of it. Suppose they meet at time lapse of t seconds after car starts. So, car travels 8 m more than the truck in t seconds...
