4m a =2 The two masses are attached as shown in an elevator accelerating upwards. a. Draw a free body diagram for each mass. (8 points) b. Derive an expression for the tension in each string. (12 points) c. Which string is more likely to break? Explain your reasoning. Note: The strings are made of the same material. (6 points) Part II: Determine if the following statements are true or false. (8 points each) Fully explain your reasoning for credit. 5. A ball smashes through a plate glass window. The force exerted on the window by the ball must have been greater than the force exerted on the hall ny the window 6. Two planets 4m and m are separated by a distance R. The force 4m exerts on m is 400 N. Therefore, the force m exerts on 4m is 100 N. 7. Suppose an ice skater carrying a mass m stands on a frictionless frozen pond. The ice skater has a mass of 10m. The ice skater heaves the mass forward with a speed The ice skater will then move backwards with a speed of 0.1v
