The velocity of the tip of the second hand on a watch if it is
Answer to Problem 91A
Explanation of Solution
Given:
The length of the second hand on the watch,
Formula used:
For a rotating and rigid object, its linear velocity( v ) can be related to its
Where r is the radius of the object.
Calculation:
Now, the second hand of the watch covers
Then, the velocity of the tip of the second hand of the watch will be,
Conclusion:
Thus, the velocity of the tip of the second hand of the watch is
