1st 9 Weeks Final Exam Review
1. Look at the following Position-Time Graph. Is the object accelerating?
 Yes
2. A basketball has a uniform acceleration of 10 m/s to 20 m/s. How far does this object
travel in 10 seconds?
 50m
3. The speed of a car is decreasing uniformly from 50 m/s to 30 m/s in 4 seconds. What is
the magnitude of the car’s acceleration?

-5m/s
4. Two astronauts on the International Space Station push against each other while in zerogravity. If Astronaut Jimmy weighs 200 kg and Astronaut Janey weighs 100 kg, who will
accelerate faster (or will acceleration be the same)?
 Janey will accelerate faster as she has less inertia than Jimmy
5. For the graph below, at which points in time is the object speeding up at a constant rate?
 0s – 3s
6. Which statement is accurate:
a. The acceleration produced is a result of a force applied to a mass.
b. Force is a result of acceleration applied to mass.
7. A ball falls from a platform and falls freely for 2.2 seconds before hitting the ground.
What is the height of the platform.

8. A plane travelling at 200 m/s west encounters a 10 m/s head wind shown in the picture
below. Will the wind slow down the plane?
 No it will not as the net force will be 190 m/s west
9. What is the mass of the object depicted in the following graph?
 20
