Chapter 2.3, Problem 1aT
Describe the motions of block A, block B, and the rope.
Expert Solution & Answer
To determine
The motions of block A, block B and the rope.
Answer to Problem 1aT
Block A, rope and Block B everything will move towards right as there is no friction between block and table.
Explanation of Solution
Introduction:
Force is defined as the rate of change of momentum. It is a pull or push on an object which is the result of interaction of an object with another object.
Two blocks A and B are tied together with a rope of mass
As the whole system is already in motion at this instant, when hand pushes block B it will move with constant acceleration and when rope will become tight, block A which was at rest also starts moving in the same direction.Block A, rope and Block B everything will move towards right as there is no friction between block and table.
Conclusion:
Thus, Block A, rope and Block B everything will move towards right as there is no friction between block and table.
