The three vehicles shown above are all traveling at a speed of 15m/s, but only the pickup truck has a changing velocity. The pickup truck has a changing velocity because the pickup truck — (8.6B)

• can accelerate faster than the other two vehicles

• is traveling in the opposite direction from the other t

• is traveling on a curve in the road

• needs a large amount of force to move

A 50 kg skater pushed by a friend accelerates 5 m/s².  How much force did the friend apply? The answer to this question is most likely (HINT: Look at the units!!!) - 

• 250 N

• 250 m/s²

• 250 kg
