An automobile and a truck start from rest atthe same instant, with the automobile initially at some distancebehind the truck. The truck has a constant acceleration of2.90 m/s2, and theautomobile an acceleration of 3.60m/s2. The automobile overtakes the truck after the truckhas moved 57.5 m.
(a) How much time does it take the automobileto overtake the truck?
(b) How far was the automobile behind the truck initially?
(c) What is the speed of each when they are abreast?
