## Homework Statement

A bird stands on a DC electric transmission line carrying 2800A. The line has 2.5 x 10^-5 ohms resistance per meter, and the bird's feet are 4.0 cm apart. What is the potential difference between the bird's feet?

## Homework Equations

I wish I knew

## The Attempt at a Solution

Alright so since the resistance is 2.5 x 10^-5

*per meter,*I found that the resistance is .000001 ohms between the bird's feet. Since the current is 2800A, I used the equation V=IR and got .0028V. Is this correct or is the problem asking for something else?

**Also, there is another problem I have**

## Homework Statement

Part A:

An electron in the picture tube of a television is accelerated from rest through a potential difference Vb-Va= 3000v. What is the change in electric Potential energy of the electron?

Part B:

What is the speed of the electron as a result of this acceleration?

## Homework Equations

W=q(Vb-Va)

## The Attempt at a Solution

I solved part A using the equation stated above and got 4.8 x10^-16

The part that I need help with is Part B. What equation should I use to find the speed?
