Ahh I see what you mean. I can solve for one of the variables and plug it back into the other equation then I would only have one variable instead of two different variables. Thank you! I understand now!
Ahh thank you! saying that even profs and grad students have the same problems made me...
Yes. Sorry that was a typo. However I am still a little unsure of how to solve systems of equations. Lemme try answering your questions:
-I know the masses and initial velocities of both objects.
-I am trying to find the final velocities of both objects.
-I think the masses seem irrelevant...
I found the momentum of the first ball and the momentum of the second ball, but there are two variables to be solved for.
Yes he gave us this equation in the case that it is elastic and both objects are in motion.
Im considering that I would need to use the conservation of momentum and...
Homework Statement
A 0.06kg tennis ball, moving with a speed of 2.50 m/s, collides head-on with a 0.09kg ball initially moving away from it at a speed of 1.15m/s.Assuming a perfectly elastic collision,what are the speed and direction of each ball after the collision?
Homework Equations...
Thank you for the warm welcome! =)
What I'm confused about is the max friction force. How do i know what the max friction force is?
I kind of understand what you are saying so let me take a stab at it. If I use the Fnet=Fapp-(Fparallel+Ffriction) formula then Fnet would equal 0 because...
The problem states: An 800N box rest on a surface inclined 30 degrees. If a force 200N parallel to the surface is applied, the box will not slide down the incline. Whats the greatest force that can be applied to the box before it starts sliding up the incline??
I know Fnorm=mg*cos theta...
