An object has a relativistic momentum that is 7.3 times greater than its classical momentum.

What is its speed?

Express your answer using two significant figures.

v=__________c

Expert Solution

Relativistic momentum P = 7.3 ( classical momentum)

(m _o v) / [1 -(v ² / c ² ) ] ^1/2 = 7.3 m _o v

(m _o ) / [1 -(v ² / c ² ) ] ^1/2 = 7.3 m _o

1 / [1 -(v ² / c ² ) ] ^1/2 = 7.3

[1 -(v ² / c ² ) ] ^1/2 = 1 / 7.3

= 0.1369

[1 -(v ² / c ² ) ] = 0.0187

(v ² / c ² ) = 0.9812

v / c = 0.9905

v = 0.9905 c

v = 0.99 c

As a red giant, the Sun’s luminosity will be about 2000 times greater than it is now. Calculate the surface temperature of the Earth under these conditions assuming that the Earth is still at 1 AU and that the photosphere of the sun is well within 1 AU. the answer should be about 1900 K but im not sure what am i getting wrong in my calculations, please help!
