Kinematics 3 (Graph of motion)

The uniform motion of a cart is shown in the distance

versus time graph below. What is the average speed of

the cart?

• 0.5 m/s

• 2 m/s

• 5 m/s

• 50 m/s

The graph below represents the relationship between

distance and time for an object. What is the average speed of the object at t = 5.0 to t = 6.0 seconds?

• 0 m/s

• 2 m/s

• 4 m/s

• 5 m/s

The graph represents the motion of a cart. According

to the graph, as time increases, the speed of the cart.

• constant

• undefined

• increase

• decrease

The displacement-time graph below represents the

motion of a cart initially moving forward along a

straight line.

During which interval is the cart moving forward at

constant speed?

• AB

• BC

• CD

• DE

Graph below which represents the displacement of an object as a function of time. What is the average velocity of the object from t = 0 to t = 2 seconds?

• 3.0 m/s

• 2.5 m/s

• 2.0 m/s

• 1.5 m/s
