A moving object with a mass of 2.4 kg has a kinetic energy of 278 J. What is its velocity?
Answered by STEM Helper
Um...I believe there should be a velocity formula but I don't know it. Sorry
Answered by PP
idk what it is im just in a science class doing a test
Answered by STEM Helper
Ok, it is v = u + at (I am going to let you do it as I fear that both of our school's code of conduct will be violated)

KE = 1/2 *mv^2

You know, STEM, chiming in just to say that you can't help just clutters up the conversation. It is assumed that someone who can help will do so when they have the time. Imagine if the dozens who look at the problem all just pop in to say "idk." What a waste of time for those who are looking for posts they can help with.

Since I recently became "famous" I'm afraid that people will be asking for MY help. But yeah, I guess I could skimp the idk.

STEM helper, if you do not know the difference between velocity resulting from a constant acceleration and kinetic energy, you need more STEM training before confusing younger students.

Actually you could call me a younger student...I just try my best to help others. If I had caused any confusion, I would greatly apologize that person.
