At the same instant, a truck traveling with a constant speed of 18.0 m/s overtakes and passes the automobile. A. How far beyond the starting point does the automobile overtake the truck? B. How fast is the automobile traveling when it overtakes the truck?

How fast is the automobile traveling when it overtakes the truck?

Explanation / Answer

Distance traveled by automobile = ut +at2/2 =0 + 2t2/2 = t2 m So as it overtake , distance traveled will be same for both , => 18t = t2 => t = 18 sec So Distance traveled = 18t = 324 m b)Velocity of automobile = u +at = 0 + 2*18 = 36 m/s
