escape velocity = squareroot(2gr)
where:
g = gravity = 10m/s
r = radius of the planet = 8×10^5 m
escape velocity = squareroot(2x10x 8×10^5 )
escape velocity = squareroot(2x 8×10^6 )
escape velocity = squareroot(16×10^6 )
escape velocity = 4000m/s

escape velocity (e)= √2gr

where:
g = 10m/s

r = 8×10^5 m

e = √(2x10x 8×10^5 )

= √(2x 8×10^6 )

= √(16×10^6 )

e = 4000ms^-1

⇒3x / 4 - 7 / 4 = 5x +12
⇒3x / 4 -5x = 12 + 7 / 4
⇒(-17x) / 4 = 55 / 4
⇒x = (55 / 4) * (4 / (-17))
= -55 / 17
