Radio signals travel through space at a speed of 300,000 km/s. A signal sent from a space probe near Mars takes 780 seconds to reach Earth.

Calculate, in kilometers, how far the space probe is from Earth.

d = 234,000,000 km

A bicycle is moving at a constant velocity of 8 m/s. How much time does it take for the bicycle to cover a distance of 80 meters? How much distance will the bicycle cover in 1 minute?

t = 10 s

d = 480 m

200

What would the displacement-time graph of no motion look like? 

a) a horizontal line 

b) the slope of the line increasing steadily 

c) the slope of the line decreasing steadily 

d) the line of the graph would increase and decrease.

a) a horizontal line

200

What is the difference between a position-time graph and a displacement-time graph? 

No difference, it is two names to describe the same graph (trick Q!)

200

Who fell down during the race, and at what time did she fall down, based on the distance-time graph of a race pictured above?

Person C at t = 6s

200

On another planet, the acceleration due to gravity is 20 m/s2.  If I drop an object from rest on that planet, what will its velocity be after 6 seconds?

v= -120 m/s

200

A car is moving at an initial velocity of 10 m/s.  It crashes into a brick wall, coming to a complete stop. If the crash crumples the car by 3 m, calculate the sudden deceleration of the car.

a = -16.67 m/s2

300

Distance is always...

 a) Equal to displacement
 b) Greater than or equal to displacement
 c) Less than or equal to displacement
 d) Negative if you travel backward

 b) Greater than or equal to displacement

300

Why is it possible to have zero average velocity and yet have a non-zero value for average speed?

If the displacement is zero, and the distance traveled is not zero, this means that an object moved in a path leading to its return to the starting point.

Ainsley is walking her dogs.  She walks them 50 m to the right, then the dogs tug her back 50 m to the left. She then pulls the dogs back to the right, moving 70 m. 

Draw Ainsley’s path during her walk and compute her total distance and displacement.

d = 170

ΔX = 70

Julia and Aditi are playing miniature golf. Julia's ball rolls into a long, straight upward incline with an initial velocity of 2.95 m/s and accelerates at -0.876 m/s2 for 1.54 seconds until it reaches the top of the incline. Determine the length of the incline.

d = 3.5 m

What is the difference between average speed and average velocity?

a) they are the same

b) average speed is the magnitude of average velocity

c) average speed is distance/time and average velocity is displacement/time
