Can classical physics be used to accurately describe a satellite moving at a speed of 7500 m/s? Explain why or why not.
A. Speed of light is 3 X 10^(8) m/s. So, 1% of the speed of light is 3 X 10^(6) m/s which is higher than 7500 m/s. The Satellite is big enough to be observable by human eyes. The gravitational force on it due to Earth which is weak. So, a satellite moving at a speed of 7500 m/s can be described accurately by Classical Physics.
B. Speed of light is 3e5 m/s. So, 1% of the speed of light is 3e4 m/s which is lower than 7500 m/s. The Satellite is big enough to be observable by human eyes. The gravitational force om it due to Earth which is weak. So, a satellite moving at a speed of 7500 m/s can be described accurately by Classical Physics.
C. Speed of light is 3e9 m/s. So, 1% of the speed of light is 3e7 m/s which is higher than 7500 m/s. The Satellite is big enough to be observable by human eyes. The gravitational force om it due to Earth which is weak. So, a satellite moving at a speed of 7500 m/s cannot be described accurately by Classical Physic
