At the instant the traffic light turns green, an automobile starts with a constant acceleration a of 1.8 m/s2. At the same instant a truck is 14.0 m down the road and traveling with a constant speed of 8.7 m/s. (a) How far beyond the traffic signal will the automobile overtake the truck? (b) How fast will the automobile be traveling at that instant?

At the instant a traffic light turns green, a car that has beenwaiting at an intersection starts ahead with a constantacceleration of 3.20 m/s^2. At the same instant a truck, travelingwith a constant speed of 20.0 m/s, overtakes and passes thecar.
(a) How far beyond its starting point does the car overtake thetruck?
(b) How fast is the car traveling when it overtakes thetruck?
(c) Sketch an x-t graph of the motion of both vehicles. Take x=0 atthe intersection.
(d) Sketch a vx-t graph of the motion of both vehicles.

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 2.11 m/s^2, and the automobile an acceleration of 3.41 m/s^2. The automobile overtakes the truck after the truck has moved a distance 41.0 m How much time does it take the automobile to overtake the truck?

A car is stopped at a traffic light. The light turns green, and at time t = 0 the car starts moving and travels with a constant acceleration. At that instant a truck traveling at a constant velocity is alongside the car, where each vehicle is positioned at x = 0. The truck passes the car, but the at later catches up to the truck in front of a house, such at time t = D, the front of each vehicle is positioned at X = D. How would a velocity graph of both vehicles look like?
