WebIn Ex. 1 above, I used the conservation of energy equation in the vertical direction. I got a final velocity of 19.84 m/s then divided by sin 45 and got close to the same answer (28.05 m/s instead of 28.16 m/s). Why is the direction not considered? WebΔ U = U orbit − U Earth = − G M E m R E + 400 km − ( − G M E m R E). We insert the values m = 9000 kg, M E = 5.96 × 10 24 kg, R E = 6.37 × 10 6 m and convert 400 km into 4.00 × 10 5 m. We find Δ U = 3.32 × 10 10 J. It is positive, indicating an increase in potential energy, as we would expect. Significance tcrva7.2 https://andermoss.com
