Determine the time it takes for the rocket to acquire the first cosmic speed of 7.9 km / s if it moves with an acceleration of 50 m / s2.
| December 4, 2020 | education
a-acceleration (m / s * s)
v- speed (m / s)
t-time (s)
7.9 km / s we translate from the SI system t = 7900m / s
a = v / t
hence t = v / a
t = 7900/50
t = 158 seconds
