A 1.0 kg object is released from rest 500 km above the earth.
A. What is its impact speed as it hits the ground? Ignore air resistance
B. What would the impact speed be if the Earth were flat?
I don't know how to start this.
I said that v=sqrt(2G*M_e*m/(R_e+300))= 1.33*10^9 but that is incorrect...I'm probably being stupid but please help
