We have no idea. We need to examine the experimental set-up. You've given us no information, except that there may have been some sort of collision.
If you move south at 30 m/s for 30 minutes, your displacement is
D = (30 mtr/s) x (30 min) x (60 sec/min)
D = (30 x 30 x 60) (mtr-min-sec/sec-min)
D = 54,000 meters south
D = <em>54 km south</em>

Пояснение:
Используя уравнение движения S = ut + 1 / 2at², где;
U - начальная скорость = 15 м / с
а - ускорение
s - пройденное расстояние = 20м
t - время = 15 секунд
подставляем в формулу заданные параметры
20 = 15 (15) + 1 / 2a (15) ²
20 = 225 + 225a / 2
20 = 225 + 112,5a
20-225 = 112,5a
-205 = 112,5a
а = -205 / 112,5
а = -1,82
Отсюда ускорение -1,82
Answer:
Speed=28.1m/s(to 3s.f.) , Time=2.19s(to 3s.f.)
Explanation:
Time=Distance/Speed
=14.5/6.63
=2.19s(to 3s.f.)
Acceleration=Final Velocity(v)-Initial Velocity(u)/Time
9.81=v-6.63/2.19
v-6.63=21.5
v=28.1m/s
Answer:
Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum. Using the templates and instructions provided by two different types of RNA, ribosomes synthesize a variety of proteins that are essential to the survival of the cell.
Hopefully, this helped! :D
