velocity time graphs

Describe the motion in section D.

A curve on a velocity-time graph shows that the acceleration is __________.

Calculate the acceleration in section A

Calculate the distance travelled in section D

Calculate the distance travelled in section C.

The deceleration from 5-7s is ______m/s².

Calculate the total distance traveled in the first 3s.

Which velocity-time graph best matches with position-time graph 1?

• 
• 
• 
• 
• None of them.

Which velocity-time graph best matches with position-time graph 2?

• 
• 
• 
• 
• None of them.

8.) From 9 to 12 seconds the average velocity of the person was ...

• 1 m/s

• -1 m/s

• 3 m/s

• -3 m/s

Answer explanation

xf-xi= (-8)-(-5)=-3m,

tf-ti= (12-9) = 3sec

so -3/3 = -1 m/s
