Answer: a = 0.647 m/s^2
Explanation:
Acceleration = change in speed / time → a = 22 / 34 → a = .647 m/s^2
Answer:
8.25 m/s
Explanation:
From the fundamental equation of motion, velocity is rate of change of displacement per unit time
![Velocity=\frac {Displacement}{time}](https://tex.z-dn.net/?f=Velocity%3D%5Cfrac%20%7BDisplacement%7D%7Btime%7D)
Given information
Displacement=2862 m
Time=347 s
Substituting the given information we obtain
![Velocity=\frac {2862 m}{347 s}=8.247838617\approx 8.25 s](https://tex.z-dn.net/?f=Velocity%3D%5Cfrac%20%7B2862%20m%7D%7B347%20s%7D%3D8.247838617%5Capprox%208.25%20s)
The correct answer is <span>nebula forms → nebula collapses → protostar forms → fusion begins</span>
Search up criterion and look at the examples and then read it and then make it in your own words
1. the max height is solved from v = square root of 2 gy where g is equal to 9.8 m/s2/ hence y is equal to 8.62 meters.
<span>
2. time at max height is solve when velocity = 0. ( 0 = -9.81*t +13); t = 1.325 seconds
3. time required for the entire trip is 2*1.325 equal to 2.65 seconds.
4. without air resistance, the velocity just before the ball hits the ground is the same as its initial velocity, 13 m/s.</span>
