The tiger's position at time <em>t</em> is given by
<em>x</em> (horizontal) = (4.5 m/s) <em>t</em>
<em>y</em> (vertical) = 7.5 m - 1/2 <em>gt</em> ²
Solve <em>y</em> = 0 for <em>t</em> to find the time it takes for the tiger to reach the ground :
0 = 7.5 m - 1/2 (9.8 m/s²) <em>t</em> ²
===> <em>t</em> = √(2 (7.5 m) / (9.8 m/s²)) ≈ 1.2 s
Evaluate <em>x</em> at this time :
<em>x</em> = (4.5 m/s) (1.2 s) ≈ 5.6 m
The image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.
<h3>What is a vector quantity?</h3>
The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
Examples of vector quantities are displacement, velocity acceleration, force, etc.
Thus, the image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.

Answer:
Concept: Physical Concepts
- A larger acceleration, which is the change in velocity divided by the change in time is the theta or the angle that it climbs to.
- Secondly the launch velocity is higher or faster and traveles a further distance.
Because if you're not truthful about your results then the science community will never believe anything else you publish even if it's true.
For the same wave, the product product of
(wavelength) times (frequency)
is always the same number. (It happens to be the speed of the wave.)
So if one of them changes, the other one has to change in the opposite
direction, in order to keep their product constant.
For electromagnetic waves, higher frequency means higher energy.
I'm not sure about mechanical waves just now.
