Problem: A projectile is launched vertically from the surface of the earth with an initial speed v0 = 6.75 km/s.
Part I: What is the magnitude of its acceleration (m/s2) 1620 km above the surface of the earth?
Part II: At what height (km) will it stop and begin to fall back to the surface of the earth?
Please show all work I think I have the answer just not positive. Thanks.
