Question

Define escape velocity. Find the expression for escape velocity. Find its value on the surface of earth.​

Answer 1

Answer:

The escape velocity (earth), ve = √2 × 9.8 × 6.4 × 106. Therefore, ve = 11.2 × 103 m/s = 11.186 km/s or 11.2 km/s (Approximately).

Body: Escape Velocity in Km/s

Earth: 11.2 km/s

Moon: 2.38 km/s

Sun: 618 km/s
