In a tv set, an electron beam moves with horizontal velocity of 4.3 x 10^7 m/s across the cathode ray tube and strikes the screen, 43 cm away. the acceleration of gravity is 9.8 m/s^2. how far does the electron beam fall while traversing this distance? answer in units of m

Explanation:

From the exercise we have initial velocity on the x-axis, the final x distance and acceleration of gravity.

From the equation on moving particles we can find how long does it take the electron beam to strike the screen

Since and

Solving for t

Now, from the equation of free-falling objects we can find how far does the electron beam fell

The negative sign means that the electron beam fell from its initial point.

the force on the thing and the distance the force moves the thing

reserve is the answer
