Solve the all parts of following question given below:
Question: A projectile is launched vertically from the surface of the earth with an initial speed v0 = 6.02 km/s.
Question 1: What is the magnitude of its acceleration (m/s2) 1920 km above the surface of the earth?
Question 2: At what height (km) will it stop and begin to fall back to the surface of the earth?
Please show the work for the calculation so I can understand what I'm doing. Thanks!
