Textbook Question
Chapter 4, Problem 52P
A biologist is studying the growth of rats on the Space Station. To determine a rat’s mass, she puts it in a 320-g cage, attaches a spring scale, and pulls so that the scale reads 0.46 N. If rat and cage accelerate at 0.40 m/s2, what’s the rat’s mass?

Mary applies a force of 70 N to push a box with an acceleration of 0.60 m/s2. When she increases the pushing force to 82 N, the box's acceleration changes to 0.80 m/s2. There is a constant friction force present between the floor and the box.
What is the mass of the box in kilograms?
K01
A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance.
The student hits the elevator button and it begins to move upwards. While the elevator is accelerating upwards, the electronic balance reads 292.0 g. What is the acceleration of the elevator?
Consider:
UP to be (+), DOWN to be (-) and g =9.8 m/s2 .
Give your answer in m/s2 to 1 decimal place

- A woman in a lift is trying to weigh a parcel with a spring scale. The lift accelerates downwards at 1.7 m/s, then travels at a constant speed of 3 m/s, and finally decelerates at 1.1 m/s. During the first stage of the motion, the scale reads 6.6 kg. Note: a spring scale is a device for measuring weight, where the parcel is suspended below a spring that is attached to a dial. The extension of the spring is proportional to the weight of the parcel, but the dial is calibrated to give the mass of the parcel in kilograms. The dial will only give the correct mass if the parcel is subjected to the Earth's normal gravity. What does the scale read during the other stages of the motion? Second Stage kg. Third Stage kg.
