9. A person who weighs 600 N stands on a scale in an elevator. The elevator is identical in all cases. The velocity and acceleration of the elevators at the instant shown are given. Rank the scale reading. Explain your reasoning. D 11. For the following situations, determine if the car is speeding up, slowing down, or staying at a constant speed and turning clockwise, counterclockwise, or not turning. 4 v = 3 m/s a = 2 m/s af 10. A 0.5-kg ball is suspended from a ceiling by two strings. The ball is at rest. a. Is the tension in string 1 greater than, less than, or the same as the tension in string 2? Explain your reasoning. Physical Scenario V B D v = 3 m/s a = 2 m/s Speeding Up/ Slowing Down/ Constant Speed v = 3 m/s a = 0 m/s String 1 30 v = 0 m/s a = 9.8 m/s String 2 Ball 60 Turning Clockwise/ Turning Counterclockwise/ Not Turning
