I'm assuming that you're setting KE and PE equal to one another to cancel out mass, as you mentioned, and then using that to solve for the escape velocities, and that makes sense. I have the values for the escape velocities. To escape Earth's gravitational pull, the velocity is 11.2 km/s and...

Homework Statement A projectile is fired straight away from the moon from a base on the far side of the moon, away from the earth. What is the projectile's escape speed from the earth-moon system? m_earth= 5.97x10^24kg m_moon= 7.348x10^22kg radius_earth= 6.371x10^6mHomework Equations...
