A fire spreads by transferring heat in 3 ways, Raditation, convection, and Conduction :)
Use energy conservation, since no energy is lost it must be constant.
E = 0.5mv² + mgh
At release the velocity v = 0 and the height is h.
E = 0 + mgh
At impact the height h = 0 and the velocity is v.
E = 0.5mv² + 0
Since the energy E is conserved:
0.5mv² = mgh
the mass m cancels and the equation becomes:
0.5v² = gh
h = 0.5v²/g
when g = 9.81 and v = 22:
h = 24,66
Yes this is not gonna work
Answer:
Explanation:
From the vertical movement, we know that initial speed is 0, and initial height is H, so:
solving for t:
Now, from the horizontal movement, we know that initial speed is V and the acceleration is -g/4:
Replacing values:
Simplifying:
