Answer:
How to find the maximum height of a projectile?
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...
if α = 45°, then the equation may be written as: ...
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
Explanation:
Answer:
<h2>39.2 m</h2>
Explanation:
The height of the hill side can be found by using the formula

p is the potential energy
m is the mass
From the question we have

We have the final answer as
<h3>39.2 m</h3>
Hope this helps you
Since in an electromagnetic wave the electric and magnetic fields are perpendicular to each other and perpendicular to the direction of motion, the electric field has to point in the z direction.
