Question

Value of escape velocity from
earth's surface is
Select one:
a. 7.92 m/s
b. 11.2 m/s
C. 11.2 km/s
d. 7.92 km/s​

Answer 1

Answer:

The answer is C. 11.2 km/s

Explanation:

For instance, the radius of Earth is 6,371 km . Substitute these values in the escape velocity equation v = √(2GM/R) . Calculate the result. It the case of Earth, the escape velocity is equal to 11.2 km/s .
