A rocket is being launched from the surface of the Earth with the aim of completely breaking free from the planet's gravitational pull without needing extra thrust after takeoff. Given that the mass of the Earth is roughly 5.97 x 10^24 kg and the radius of the Earth is about 6.37 × 10^3 km, what is the minimum speed that the rocket must reach to achieve escape velocity?a.
14,320.90 metres per second.
b.
9,500.25 metres per second.
c.
12,180.75 metres per second.
d.
10,440.50 metres per second.
e.
The minimum speed that the rocket must reach to achieve escape velocity is 11,176.62 metres per second.
