Please Help! Tension Pull problem w/friction
Hello all, I am having a bit of trouble on this for some reason.
On a horizontal plane, a 10kg box and a 20kg box are tied together by a rope, and the 20kg box is being pulled by another rope with a force of 200N. The coefficient of friction is 0.500
1. What is the acceleration of the blocks?
2. What is the tension in the rope connecting the boxes?
3. What is the change in KE?
4. What is the change in thermal/internal energy of the block/floor
system?
I know the answers to the questions, but need to know how to find them, especially question #2.
Thanks in advance,
Jason
