At the instant the traffic light turns green, a car that has been waiting at an intersection starts ahead with a constant acceleration of 3.2 m/s2 . At the same instant a truck, traveling with a constant speed of 20 m/s overtakes and passes the car at the same intersection. The car eventually overtakes the truck. Draw a motion diagram for both the car and the truck. 1. How far beyond its starting point does the car overtake the truck?

2. How fast is the car traveling when it overtakes the truck?

1. Show ALL equations, then substitution of numerical values with units.

2. If you have a string of numbers with no preceding equation, sketch, or explanation, you will receive NO CREDIT even if it leads to the correct answer.

3. Make sure all symbols used are clearly identified on your sketch. BOX each required answer. Show work in a Logical Order – Don’t jump around.
