Question

At the instant the traffic light turns green an automobile that has been waiting at an inter section starts a head with a constant acceleration of 2m/s square. At the same instant a truck. traveling with a constant velocity of 10m/s, overtakes and passes an automobile. How far beyond its starting point will the auto mobile overtake the truck?​

Answer 1

100 m

Step-by-step explanation:

Distance truck will travel = 10 m/s * t sec

Distance car will travel = 1/2 at^2

find when these two are equal

10t = 1/2 (2) t^2

t^2 -10t = 0

shows t = 10 sec

In 10 sec the truck travels 10 m/s * 10 s = 100 m
