Hey there, I'm lost with this one:
Now, I know how to go about calculating the velocity of the center of mass (v(cm)= m(1)V(1)+m(2)V(2)/m(1)+m(2)
The thing that throws me off is the j-hats and i-hats. How do I come out with a vector number? I thought of the pothagarem(sp?) therom, but...
Hey guys, just a quick question. If you have a pendulum of length L and a bob of mass M, and if you bring the string to a horizontal position and then give the bob a minimal initial speed enabling the pendulum to make a full turn... the maximum kinetic energy of the pendulum will be when it...
Hi guys, I'm new :smile:
Now, I came here in search of help to a homework problem I have. I've tried to solve for around 40 minutes now, and can't get past solving for k. Here's the problem.
The way I'm trying to solve is is by setting up two parts. One, I just solve for K in general...
