The velocity at the maximum height will always be 0. Therefore, you will count your final velocity as 0, and your initial velocity as 35 m/s. Next, we know that the acceleration will be 9.8 m/s^2. How? Because the ball is thrown directly upward, and the only force acting on it will be the force of gravity pushing it back down.
The formula we use is h = (Vf^2 - Vi^2) / (2*-9.8m/s^2)
Plugging everything in, we have h = (0-1225)/(19.6) = 62.5 meters is the maximum height.

Is this for zoommmmmmmmmm?
Explanation:
It had to be 20 letters I had to do something
Answer:
<em>63.44 rad/s</em>

Explanation:
mass of bullet = 3.3 g = 0.0033 kg
initial velocity of bullet 
= 250 m/s
final velocity of bullet 
= 140 m/s
loss of kinetic energy of the bullet = 
==> 
= 70.785 J
this energy is given to the stick
The stick has mass = 250 g =0.25 kg
its kinetic energy = 70.785 J
from
KE = 
70.785 = 
566.28 = 
= 23.79 m/s
the stick is 1.5 m long
this energy is impacted midway between the pivot and one end of the stick, which leaves it with a radius of 1.5/4 = 0.375 m
The angular speed will be
Ω = v/r = 23.79/0.375 =<em> 63.44 rad/s</em>
D. mechanical energy is transformed into sound energy.
Answer:
it is constant because there is not any force that oppose the horizontal motion
but the vertical velocity is not constant because there is a gravitational force that oppose the motion .
