Answer:
a = 1.16 m/s²
Explanation:
In order to find the acceleration of the ball we will use 3rd equation of motion.
2as = Vf² - Vi²
where,
a = acceleration = ?
s = displacement = 21.9 m
Vf = Final Velocity = 7.14 m/s
Vi = Initial Velocity = 0 m/s (Since, ball starts from rest)
Therefore, using the values, we get:
2a(21.9 m) = (7.14 m/s)² - (0 m/s)²
a = (50.97 m²/s²)/(43.8 m)
<u>a = 1.16 m/s²</u>
Whan object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations.
I think d because the water can make the humidity go down and make the air cool
Answer:
The distance the piece travel in horizontally axis is
L=3.55m
Explanation:





Now the angular velocity is the blade speed so:
assuming no air friction effects affect blade piece:
time for blade piece to fall to floor

Now is the same time the piece travel horizontally

blade piece travels HORIZONTALLY = (24.5)(0.397) = 9.73 m ANS
