Answer:
La única manera en que nuestro astronauta sería capaz de empujar la nave espacial en el espacio sin alejarse sería usar algo llamado "unidad de propulsión de astronauta". Supongamos que el astronauta está usando un SPK soviético, el sistema de cohetes mochila más poderoso jamás utilizado en el espacio.
Explanation:
Answer:
velocity = 0.3m/s
speed = 1.21 m/s
Explanation:
The total time it takes to get from the front door to the bench is
t = 27 + 39 = 66 seconds
The net displacement from the front door to the bench is the distance from the front door to the windmill subtracted by the distance from the windmill to the bench
s = 50 - 30 = 20 m
So the average velocity is net displacement divided by total time
v = s / t = 20 / 66 = 0.3 m/s
The total distance from the front door to the bench is the sum of distance from the front door to the windmill and the distance from the windmill to the bench
S = 50 + 30 = 80 m
So the average speed is total distance divided by total time
v = s / t = 80 / 66 = 1.21 m/s
Answer:
a)
Explanation:
because you said time which is speed and acceleration which space
