$300 Answer from Graphs

$400 Question from Graphs What does the horizontal line represent in Graph A? What does the horizontal line represent in Graph B? AB

$400 Answer from Graphs Graph A – Staying still (not moving) Graph B – Constant speed AB

$500 Question from Graphs What is the average speed of the marble? What is the speed at 3 seconds?

$500 Answer from Graphs Average speed = 10 meters/7 seconds = 1.43 m/s Speed at 3 seconds = 4 meters/3seconds = 1.33 m/s

$100 Question from Speed & Velocity What is speed? How do you calculate speed?

$100 Answer from Speed & Velocity Speed is the rate of motion; the distance an object travels in a unit of time Speed (m/s) = Distance (meters) Time (seconds)

$200 Question from Speed & Velocity Bart ran 5,000 meters from the cops at an average speed of 6 meters/second before he got caught. How long was he running?

$200 Answer from Speed & Velocity Speed = Distance Time Rearrange the formula Time = Distance Speed 5, 000 meters = seconds 6 m/s

$300 Question from Speed & Velocity What is the speed of a walking person in m/s if the person travels 1000 m in 20 minutes?

$300 Answer from Speed & Velocity 20 minutes x 60 seconds = 1,200 seconds 1 minute 1,000 meters = meters/second 1,200 seconds

$400 Question from Speed & Velocity If Justin races his BMW M5 down I-71 for 2,560 meters in 60 seconds, what is his average speed?

$400 Answer from Speed & Velocity 2,560 meters = meters/second 60 seconds

$500 Question from Speed & Velocity Which of these 3 lines has the fastest average speed?

$500 Answer from Speed & Velocity m/s m/s m/s
