The vertical velocity is the greatest at C, where it is closest to the ground.
The projectiles horizontal velocity stays constant through the entire thing, so it is the same for A, B, and C.
The projectiles speed is the greatest at C, because both its vertical and horizontal components of its velocity is greater than or equal to that of the other two points.
<h3><u>Answer;</u></h3>
M.A = 4.25
<h3><u>Explanation;</u></h3>
Mechanical advantage is the ratio of the force required to do something in comparison to the actual force required using a simple machine.
It is the ratio of output force to the input force.
M.A = Output Force/ Input Force
Out put force 85 Kg = 850 N
Input force = 200 N
Therefore;
M.A = 850 N/200 N
= 4.25
False, the wavelength decreases as the frequency increases
