Answer:
A) 4037.2[km]; B) 21472[m/s]
Explanation:
A)
This part can be solved using the principle of energy conservation, where kinetic energy will be equal to potential energy. We will define the kinetic energy and the potential energy.
Now we have to match both equations in this way the mass value is canceled and we can clear h.
B)
To solve this problem we can use the kinematic equations, but first we must identify the initial data:
yo = 2.35*10^7[m]
y = 0 [m] when hit the ground [m]
vo = 0 [m/s], It is essentially at rest...
