Hi I need help on these questions, please try to be specific.
A sled dog pulls 2 sleds, A and B
mu=0.10
If tension in rope 1 is 150 N
What is the tension in rope 2?
-----------------------------------
Mass 1 on a table (mu=0) is connected by string through a hole in the table to a...
circular motion!
two wires are tied to a 200g ball. the ball revolves in a horizontal circle at a constant speed of 7.5 m/s. what is the tension in each wire.

!Nonuniform Circular Motion
a 500 g ball rotates on a table while attached to a 1.2 m long tube. A force of 4 N is applied perpendicularly to the end of the tube. the max tension the tube can withstand is 50 N. if the ball starts from rest, how many revolutions does it make before breaking...
