Question

calculati viteza medie a navei Apollo 8 daca in 4 zile a ajuns pana la luna la distanta de 400000 km​

Answer 1

$v_{medie} = \frac{distanta}{timp}$

8 zile = 192 ore

$v = \frac{400000}{192} = 2083.33\ km/h$

► In S.I :

400000 km = 400000000 m

4 zile = 345 600 secunde

v = 400000000 / 345600 = 1157.407 m/s
