An astronaut sits on a chair that vibrates horizontally at the end of a string. A motion detector determines?
An astronaut sits on a chair that vibrates horizontally at the end of a string. A motion detector determines the amplitude of vibration and the speed of the chair as it passes through equilibrium position. The spring has a 1200N/m spring constant, the amplitude of vibration is 0.5m, and the speed of the chair as it passes through equilibrium is 2m/s. Using this data what is the combined mass of the chair and the astronaut.
A!!!
C!!!
All of the above???!!
