I'm just wondering if the problem gave you any other information, because you stated this was a really hard kinematics question.
When we were working on kinematics, we worked on a similar problem, but the problem also stated the speed of sound...
If not, then it seems like a relatively...
For the second problem, I suggest you draw a picture. It's a projectile problem (you probably know this) and relatively easy to go about solving it, once you can picture it. You know that the ball is going straight into the horizontal direction, and you know y as well as Vox. If you can solve...
I was working on some gravitational force problems, and this one was particularly challenging to me:
"Two particles are located on the x axis. Particle 1 has a mass m and is at the origin. Particle 2 has a mass 2m and is at x=+L. Where on the x-axis should a third particle be located so that...
a physics question i was assigned was:
If two springs are made of the exact same material, but one is shorter than the other, why is the shorter spring stiffer than the other spring?
I know it is related to Hooke's law being that if a spring has a higher K value, it is stiffer, but I don't...
