One-Dimensional Kinematics Review

what is the speed of an object at rest?

• 0.0 m/s

• 1.0 m/s

• 9.81 m/s

• -9.81 m/s²

Velocity is (select all that apply)

• speed with a direction

• a vector

• rate of change of displacement

• rate of change of acceleration

distance is (select all that apply)

• a scalar

• how far an object moves is all of its travels

• always positive

• how far an object is from where it started

Displacement is (select all that apply)

• how far an object is from where it started

• how far an object has traveled

• a scalar

• a vector

select all of the properties that are scalars

A truck moves 70 m east, then moves 120 m west, and finally moves east again a distance of 90 m. If east is chosen as the positive direction, what is the truck's resultant displacement?

• 40 m

• -40 m

• 280 m

• -280 m

• 230 m

Calculate the acceleration for segment A.

• 2 m/s²
• 2 m/s

A person walking along a straight line moves such that her velocity as a function of time can be represented by the graph above. At what time does the person have the same position as she had at time t = 0?

• At t = 5 s

• During the interval 5 s < t < 8 s

• At t = 8 s

• During the interval t > 8 s
