A physics student who weighs 516.0Â Â N stands on abathroom scale in an elevator that is supported by an elevatorcable; the mass of the elevator, including the student inside, is868.0Â Â kg . While the student is standing on the scale,the elevator makes an upward trip, followed by a downwardtrip.
A)Find the magnitude ofthe acceleration of the elevator at the instant of time when thescale reads 449.0Â Â N
B)What is the tension in the elevator cable in Part (A)?
When the Scale Reads More than the Weight of the Student
At some time during her elevator ride, the scale reads686.0Â Â N .->>
->> C)What is the magnitude of the acceleration of theelevator if the scale reads 686.0Â Â N ?
D)In which direction is the elevator moving if the scale reads686.0Â Â N ?
