Question

What is the kinetic energy of a 1.0-kg billiard ball that moves at 5.0 m/s?

A.
5.0 J

B.
6.5 J

C.
10.0 J

D.
12.5 J

Answer 1

1/2 times mass times (velocity squared)

\[\frac12 m v^2\]

Answer 2

if you drew something or made an equation I can't see it :/

Answer 3

What is the mass of the ball?

Answer 4

1.0-kg ?

Answer 5

Yes, what is the velocity of the ball?

Answer 6

5.0 m/s

Answer 7

The equation for finding Kinetic Energy \(KE\) is half the mass \(m\) times velocity \(v\) squared.\[KE=\frac{1}{2}mv^2\]

Answer 8

I can't see the equation :/

Answer 9

KE=1/2mv^2

Answer 10

ahh okay

Answer 11

I think this is more a question on how we can fix it so that you can see LaTeX equations on your web browser.

Answer 12

Which browser are you using? Internet Explorer, Chrome, Firefox, Safari?

Answer 13

Google Chrome

Answer 14

Up in the top right there is a Settings button, three little lines, click that and pick About Google Chrome.

Answer 15

okay I did

Answer 16

Did it say you have the current version?

Answer 17

Yeah it does. It has like a green check and it says "Google Chrome is up to date"

Answer 18

Try refreshing the page with Ctrl-Shift-R

Answer 19

Okay I did

Answer 20

Can you see equations?\[like this?\]

Answer 21

nope his is what I see: \[like this?\]

Answer 22

Well, if it make you feel better, now I see it the same way. lol
It must be a problem with openstudy today. Every once in a while try refreshing with Ctrl-Shift-R and it should start working when openstudy fixes it.
