d-t & v-t GRAPHS FOR UNIFORM MOTION

A delivery t ruck took the following route that has been divided into individual lettered segm ent s A t o H. Assum e that each segm ent is covered at uniform velocit y and t hat t he road lies along a st raight port ion of an east -west highway. (A) (B) (C) (D)

East for 1/2 hour at 60 km/h. (E) West for 40 km at 80 km/h. St opped for 15 minut es making a delivery. (F) St opped for a 1/2 hour coffee break. East for anot her 30 minutes at 90 km/h. (G) East for 1/2 hour at 60 km/h. Stopped for 15 minutes making a delivery. (H) Back directly home in one hour.

1.

Use t he data to complete t he table below. Note: displacement is t he change in position for each segments while position is the delivery truck’s position with respect to it’s st art ing posit ion (hom e). displacement (km [E])

velocity (km/h [E])

t ime (hours)

posit ion (km [E] of home)

A B C D E F G H

2.

Plot a posit ion-time graph for the ent ire journey on t he d-t graph given.

3.

Plot a velocit y-t im e graph for the entire trip on the v-t graph given.

4.

What is the (i) average speed (

) and (ii) average velocit y (

) for the entire t rip?
