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 automobile has an acceleration of $3.5 m / s^{2}$ . The automobile overtakes the truck when it (truck) has moved $60 m$ . How far was the automobile behind the truck initially?

For $$automobiles2=12a2t2=12$$×$$3.5$$×$$(7.39)2$$ $$=95.5$$ m For the truck ,$$S1=12aa1t2=12$$×$$2.2$$×$$t2=60$$ ⇒$$t=7.39$$ sInitially distance between them,$$=s2-s1$$ $$=35.5$$ m
