Chapter 11, Problem 1Q
Can the diver of Fig. 11–2 do a somersault without having any initial rotation when she leaves the board?
Expert Solution & Answer
To determine
Whether the diver do somersault without having any initial rotation when she leaves the board.
Answer to Problem 1Q
No, the diver can’t do somersault without having any initial rotation when she leaves the board.
Explanation of Solution
When the diver do somersault he will be in the air so that the net torque on the diver will be zero. The zero torque will result in the conservation of angular momentum. When the person leaves the board without any initial rotation, the initial angular momentum will be zero.
In order to obey the conservation of angular momentum the final momentum must be zero so that the person is unable to do a somersault. Thus it is not possible to do a somersault without having any initial rotation when she leaves the board.
