How far was the monitor released by the frustrated computer user?

In summary, the conversation discusses how to calculate the distance at which a computer monitor was released from rest by a frustrated user on a higher floor, using the velocity and acceleration of the monitor as it passed the window and the height of the window.

Hey I was wondering if anyone can point me in the right direction of where to begin in this problem:

An apartment-dweller is looking out of the window if her living room. The glass area of the window measures 2.00m from the top and bottom. A freely-falling computer monitor suddenly drops past her window, taking exactly 0.200s to pass the window. How far above the top of the window was the monitor relseased (from rest) by the frusterated computer user om the higher floor?

Thanks a lot :)

I would first calculate the velocity of the computer as it reached the top of the window frame. With that velocity and the fact the computer started at 0 velocity you can calculate the distance that it fell

[tex]y=y_0+v_0t+\frac {1} {2} at^2[/tex]
[tex]v^2 = v_0^2 + 2a(y-y_0)[/tex]

thank you, i'll give that a try

You know how long it took to go past it her window, you know how fast it is accelerating, you know how tall her window is, so why not find how quickly it is moving when it first enters the window frame? Hope that points you in the right direction. The rest is trivial.
 

What is uniformly accelerated motion?

Uniformly accelerated motion is a type of motion in which the velocity of an object changes at a constant rate. This means that the object's speed increases or decreases by the same amount in each unit of time.

What is the equation for uniformly accelerated motion?

The equation for uniformly accelerated motion is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time elapsed.

How is uniformly accelerated motion different from constant velocity motion?

In uniformly accelerated motion, the velocity is changing at a constant rate, while in constant velocity motion, the velocity remains the same. In other words, in uniformly accelerated motion, the object is accelerating or decelerating, while in constant velocity motion, the object is moving at a constant speed.

What is the difference between average velocity and instantaneous velocity in uniformly accelerated motion?

Average velocity is the overall velocity of an object over a certain time period, while instantaneous velocity is the velocity of the object at a specific moment in time. In uniformly accelerated motion, average velocity can be calculated using the equation v = (u + v)/2, while instantaneous velocity can be calculated using the derivative of the displacement equation.

How does the angle of an inclined plane affect uniformly accelerated motion?

The angle of an inclined plane affects the acceleration of an object moving down the plane. The steeper the angle, the greater the acceleration. This is because the component of the force of gravity acting down the plane increases as the angle increases, resulting in a greater acceleration.
