Question

3. A rocket of mass 10,000 kg will have an escape velocity __________ the escape

velocity of a rocket with mass 5,000 kg.

A. one quarter of

B. one half of

C. the same as

D. double

Answer 1

here,

for the escape velocity

the escape velocity = sqrt(2 * G * M/R)

the escape velocity is independent of the mass of the rocket

therefore,

the escape velocity C. the same as the escape velocity of a rocket with mass 5000 Kg
