They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations.
To determine the height of the object given the time, we simply use the given relation between height and time in the problem statement. It is given as:
h = -16t^2 + 127t
We substitute 55 seconds to t and obtain,
h = -16(55)^2 + 127(55)
h = - 41415
Answer:
<h2>The answer is 5 s</h2>
Explanation:
The time taken can be found by using the formula

d is the distance
v is the velocity
From the question we have

We have the final answer as
<h3>5 s</h3>
Hope this helps you
A horizontal line on a speed/time graph means a constant speed.
