A certain planet with a radius of 8.30×107 m has an escape velocity of 3.60×104 m/s. What is the mass of this planet?


How do i solve this?

What is the gravitational potential needed to carry a mass m to infinity?
 
escape velocity = sqrt(2*G*M/r)
 
escape velocity = sqrt(2*G*M/r)

Throwing out a single line of text with no justification doesn't help the OP at all. We're here to help him understand not simply toss a formula his way and tell him to plug in the numbers... What use is that?
