PLEASE HELP ASAP!! THIS IS DUE IN 15 MUNITES!! Explain what a Precipitate (Not Precipitation) is and tell me if it is a Physical
1 answer:
You might be interested in
here given that object is dropped from height h = 50 m
So here we can say
initial speed is ZERO
acceleration is due to gravity
now in order to find time to reach the ground we can use kinematics
now plug in all values in it
so it will take 3.2 s to reach the ground
Answer:
It will take 30 seconds to reach the ground, and it will be travelling at 294 m/s when it does so. This means that its average velocity was 147 m/s.
Explanation:
Since the initial velocity of a dropped object is 0, we can make this the equation:
The final velocity can be calculated with the formula:
Once again, since there is no initial velocity:
Since the initial velocity is 0, the average vertical velocity is 294/2=147 m/s.
Hope this helps!
