At the instant a traffic light turns green, a car starts moving with a constant acceleration a of 4.00 m/s2. At the same instant a truck, traveling with a constant speed of 10.09 m/s, overtakes and passes the car. How far beyond the traffic light will the car overtake the truck?

At the same time a truck, traveling with a constant speed of 9.5m/s, overtakes and passes the automobile. (A) How far beyond the traffic light will the automobile overtake the truck?

Given that,
the car overtakes the truck
therefore their distance covered are equal.
distance covered by the car
x=1/2X4t^2
x=2t^2  (1)
By the truck
x=vXt
ie,x=10.09Xt 
50.45

f**k u . u even can't do this simple problem!!!
