If i have a block and i pull it with a velocty ' v ' and the block is attached to a string which makes an angle @ with the direction of velocity of block then what is the velocity of the string?
Can the velocity of the string and the block be different? Then there will be a slip or break of string. I feel it has to be same as that of block for continuity of the act of pulling.
Ofcourse the tension in the string can be resolved. Horizontal component will help in pulling while vertical component may help in reducing friction. But velocity should remain same , I feel.
