A student holds an egg outside of an open window and let's go. The window is 40 meters above the ground and the egg is falling u

nder the acceleration of gravity, which is 9.8 m/s2. There are two equations that can be used to describe its motion over time:
How far will the egg travel after 2 seconds? Be sure to use the 5 steps to solve the problem. Show which equation you used, what each variable equals, and answer the question in a complete sentence.

The distance traveled by the egg after 2 seconds is 19.6 m.

The given parameters:

  • <em>Height of the window, h = 40 m</em>

The distance traveled by the egg after 2 seconds is calculated as follows;

h = v_0_y t + \frac{1}{2} gt^2\\\\

where;

  • <em />v_0_y<em> is the initial vertical velocity of the egg = 0</em>
  • <em>g </em><em>is acceleration due to gravity = 9.8 m/s²</em>
  • <em>t </em><em>is the time of motion, = 2 s</em>

h = 0 \ + \ \frac{1}{2} \times 9.8 \times (2)^2\\\\h = 19.6 \ m

Thus, the distance traveled by the egg after 2 seconds is 19.6 m.

What are the differences and relationships between speed, velocity, and acceleration
melamori03 [73]

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

Use the fact that 1inch=2.54cm and convert 52 inches into the equivalent length in centimeters.
Lelu [443]

Answer:

To convert inches to centimeters, use an easy formula and multiply the length by the conversion ratio.

Since one inch is equal to 2.54 centimeters, this is the inches to cm formula to conver

A horizontal disk rotates about a vertical axis through its center. Point P is midway between the center and the rim of the disk
hjlf

Answer:

The answer is explained below.

Explanation:

All the point on the disk has same angular acceleration. Here, the point P is at the midway between the center and the rim of the disk and the point Q is at rim of the disk.

So, the distance of the point Q from the axis is twicee the distance of the point P from the axis.

<em>Rp - R</em>

<em>Rq - 2R</em>

The linear acceleration is

α2 - Rα

So, the linear acceleration of Q is twice as great as the linear acceleration of P.

The speed of the particle when it is in the circular motion depends on the radius of the particle.

In this case, the speed of point Q is twice the speed of point P.
