An automobile and a truck start from rest at the same instant, with the automobile initially at some distance behind the truck. The truck has a constant acceleration of `2.2 m//s^2` and the automobile has an acceleration of `3.5 m//s^2`. The automobile overtakes the truck when it (truck) has moved 60 m.
(a) How much time does it take the automobile to overtake the truck ?
(b) How far was the automobile behind the truck initially ?
(c) What is the speed of each during overtaking ?
