The escape velocity from Earth's surface is approximately:
A
7.9 km/s
B
3.6 km/s
C
5.5 km/s
D
11.2 km/s
Correct Answer: Option D — 11.2 km/s
Explanation:
Escape velocity is the minimum speed an object must have to overcome Earth's gravitational pull without further propulsion, and for Earth this value is approximately 11.2 kilometres per second.
