A particle moves from x₁ = –50 cm to x₂ = 30 cm. The displacement of this particle is

• 30 cm

• 40 cm

• 80 cm

• -80 cm

Four successive displacements of 4 km, 5 km, 4 km, and 2 km are at right angles to each other as shown in the diagram. The magnitude of the resultant displacement is

• 4 km

• 15 km

• 3 km

• -5 km

You drive for 30 min at 100 km/h and then stop for 15 min. You then drive for 45 min at 80 km/h. Your average speed for the entire trip is

• 73 km/hr

• 83 km/h

• 88 km/hr

• 90 km/hr

The displacement of an object during any time interval is ________ the distance it travels during that same time interval.

• greater than or equal to

• less than or equal to

• equal to

• greater than

An object, located at the origin when t = 0, moves along the x axis as shown in the diagram. At which point is the object farthest from its starting point?

• A

• B

• C

• D

The graph shows how the position of a particle depends on time. Which choice is closest to the average speed of the particle in the time interval between 0 and 6 s?

• 0.40 m/s

• 0.67 m/s

• 0.75 m/s

• 1.50 m/s

If the speed of object A is twice that of object B, the distance object B travels in a given interval of time as compared with object A is

• twice as great

• half as great

• the same

• four times as great

• A

• B

• C

• D

In which graph is the object the farthest from the origin at t = 5 s?

• A

• B

• C

• D
