Homework Help: Physics

Posted by JC on Sunday, September 10, 2006 at 2:16pm.

At the instant the traffic light turns green, an automobile that has been waiting at an intersection starts ahead with a constant acceleration of 2.50 . At the same instant, a truck, traveling with a constant speed of 15.4 , overtakes and passes the automobile.

How far beyond its starting point does the automobile overtake the truck?

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


Write equations for horizontal distance travelled vs time for auto and truck. Then set equal to each other and solve for the time when passing occurs. Knowing that time, you can also solve for the velocity of the accelerating auto.

I will be glad to critique your work. This is a homework HELP service. We do not DO it for you here.
