Q1 Review - Physics

Your friend takes your phone and runs down the hall. You chase her at a velocity of 3 m/s. How much time does it take you to chase her 240 m?

• 0.0125 sec.

• 80 sec

• 720 sec.

• 240 sec.

How do you calculate the velocity based on this graph?

• Use the final number from the y axis

• Use the final number from the x axis

• Calculate the slope of the line

• Calculate the areas between the line and the x axis

A kid rides her bicycle from her friend’s back home as shown on the graph below. Determine the velocity at which the girl moved.

• 30 m.

• 40 m.

• 6.7 m/s

• 5 m/s

A certain express train is capable of traveling at 85 m/s between Philadelphia and New York City. Calculate how far the train travels between the cities if the trip takes 1620 seconds.

• 137700 m.

• 2300 m.

• 3.1 m

• 8,300,000 m

What is the displacement from 0-5 seconds?

• 25 m away
• 5 m away 
• 6 m away
• 15 m away

What is the average velocity from 0-5 seconds?

• 25 m/s away
• 5 m/s away
• 1 m/s away
• 15 m/s away
