Question

How do you calculate escape speed?

Answer 1

Explanation:

1. The acceleration due to gravity (earth), g = 9.8 m/s2.

2.The radius (earth), R = 6.4 × 106 m.

3.The escape velocity (earth), ve = √2 × 9.8 × 6.4 × 106.

4.Therefore, ve = 11.2 × 103 m/s = 11.186 km/s or 11.2 km/s (Approximately).
