8. Look at the image to the right. Using the Law of Force and Acceleration, predict how acceleration would change if you changed the mass of the boy. 9. Using the same picture from #8, discuss how the Law of Inertia applies to this situation. For problem 10 - 11, you will need to identify the quantities for force, mass, and acceleration. This will require you to solve the problem for the missing variable. Don't forget to use your triangle! 10. How much force is needed to accelerate a 68 kilogram skier at a rate of 1.2 m/s? Force = Mass = Acceleration = 11. What is the acceleration of a 0.3 kg ball that is hit with a force of 25 Newtons? Force = Mass = Acceleration = 12. A blue toy car has a mass of 1.3 kg and a red toy truck has a mass of 2.1 g. Which will accelerate more when an equal amount of force is applied to each? Why? (read carefully!!!)
