ANALYZING MOTION GRAPHS
You start off to school in the morning driving at 10 m/s down a side street for 4 minutes and then hit the
main road and then go 20 m/s for 3 minutes. Unfortunately, you hit a stop light where you have to wait
for 2 minutes. You then begin driving at 20
m/s and drive for another 5 minutes until you get to your
friend’s house. You have to wait for him to shower and get dressed which takes 5 minutes. You then have to
bactrack towards the school so you drive at 25 m/s for 3 minutes. You cruise into the lo
t just in time to
hear the 7:30 bell ring. Doh! Late again. . . .

1. Outraged at the
sight of seared animal
flesh being consumed in the backyard,
Lisa Simpson feels she must put an end to
Homer’s backyard BBQ. She pushes the
wheeled barbecue carrying the “pig de
resistance” at a speed of 4 m/s while Homer and Bart give
chase. When she re
aches a hill, she loses control of the pig
and it rolls down a hill. The pig reaches a speed of 34 m/s in
a time of 8 sec. Find the pig’s acceleration.
2. How far did the BBQ grill roll?
3. The pig reaches a level part of the road where friction
slows the pig down somewhat. The speed decreases to 20
m/s in 7 seconds. Determine this acceleration.
4. The cart hits a Duff can lying in the road which gets
stuck in the wheel causing the cart to slow down at a
greatly increased rate. It comes to
a stop in 8 seconds. Find
out how far the barbeque moves during this time.
5. The pig has unfortunately come to a
stop in the middle of a bridge. Just
before Homer reaches it, a sugar truck
hits the pig sending it over the bridge and it
begins to a
ccelerate from rest at a rate of 9.8 m/s/s. It
strikes the water, 25 meters below.
How fast is the pig going just before he hits the water?
