Motion Pretest

A man jogs at a velocity of 2.5 m/s west for 1200 seconds. He then walks at a velocity of 1.0 m/s east for 500 seconds & then stops to rest. What is the displacement of the man when he stops to rest?  $v\ =\ \frac{d}{t}$  

• 3500 m west

• 3000 m west

• 2500 m west

• 700 m west

Which best describes the motion of the object shown in this graph?

• It is moving at a constant speed

• It has a changing speed

• It is slowing down

• It is stopped

• starting position

• acceleration

• direction

In which of the following conditions does the car NOT accelerate?
