A remote control car is being driven along a straight track at 3 m/s. The child
controlling the car then activates the toy’s turbo mode so that, 5 seconds later, the
car’s speed is 4.2 m/s. What is the car’s average acceleration?
Identify the variables and solve each of the following problems:
Suppose you are walking home after school. The distance from school to your home is
five kilometers. On foot, you can get home in 25 minutes. However, if you rode a
bicycle, you could get home in 10 minutes. What is your average speed while
bicycling?
Juan’s mother drives 7.25 miles southwest to her favorite shopping mall. What is the
average velocity of her automobile if she arrives at the mall in 20 minutes?

Identify the variables then solve each of the following problems:
While traveling along a highway, a driver slows from 24 m/s to 15 m/s in 12 seconds.
What is the automobile’s acceleration? (Remember that a negative value indicates a
slowing down or deceleration.)
A parachute on a racing dragster opens and changes the speed of the car from 85
m/s to 45 m/s in a period of 4.5 seconds. What is the acceleration of the dragster?

Identify the variables and solve each of the following problems:
A helicopter’s speed increases from 25 m/s to 60 m/s in 5 seconds. What is the
acceleration of this helicopter?
As she climbs a hill, a cyclist slows down from 25 mph to 6 mph in 10 seconds. What is
her deceleration?
Do you think this is true? Why or why not?
