The three vehicles are all traveling at a speed of 10 m/s, but only the pickup truck has a changing velocity. The pickup truck has a changing velocity because the pickup truck -

• needs a large amount of force to move

• can accelerate faster than the other two vehicles

• is traveling in the opposite direction from the other two vehicles

• is traveling on a curve in the road
