2. A person weighs a 5.0 kg fish using a spring scale attached to the ceiling of an elevator. What does the spring scale read in Newtons when the elevator is accelerating upwards at 2.0 m/s?? What does the spring scale read when the elevator is moving at a constant velocity of 3.0 m/s? 3. A 1 kg hanging mass is connected by a string over a pulley to a 2 kg block resting on a flat, smooth table. Calculate the acceleration of the system and the tension in the string. Be sure to include complete free body diagrams for each block in your solution. 4. A block is placed on a 30° ramp and is observed to slide down the ramp with an acceleration of 2 m/s?. What is the coefficient of friction between the block and the ramp?
