Explanation:
<u>Horizontal Launch</u>
When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled by gravity until it eventually hits the ground.
The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:
vx=v
The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:
The horizontal component of the velocity is always the same:
The vertical component at t=5.5 s is:
Answer:
Explanation:
We are going to use the accelerated motion formula on the vertical component taking the upwards direction as positive.
Since <em>at maximum height the speed will be </em>, the formula can be written as
, which for our values is:
Written to three decimal places.
