Question
Please Help! Answer each with either Greater Than, Less than, or Equal To.
The Flintstones and Rubbles decide to try out the new inclined bowling alley, ``Bedslant Bowling''. Betty's ball and Wilma's ball have the same size, but Wilma's ball is hollow. Fred's ball and Barney's ball are scaled down versions of Betty's ball and Wilma's ball respectively. They all place their bowling balls on the same pitch incline and release them from rest at the same time.
1. The time it takes for Wilma's ball to hit the pins is .... that for Barney's ball to hit.
2. The time it takes for Barney's ball to hit the pins is .... that for Fred's ball to hit.
3. The time it takes for Wilma's ball to hit the pins is .... that for Betty's ball to hit.
4. The time it takes for Barney's ball to hit the pins is .... that for Betty's ball to hit.
5. The time it takes for Fred's ball to hit the pins is .... that for Wilma's ball to hit.
6. The time it takes for Betty's ball to hit the pins is .... that for Fred's ball to hit.
Explanation / Answer
Fred's ball has more mass compared to barney's ball which is hollow... so it has more inertia...
the inertia values...
F > B
Wilma's ball is small than Fred's ball so inertia of wilma will be less than Fred but since it is not hollow it will be greater than Barney...
So F > W > B
Betty's ball is hollow as well as small so it will have very less inertia...
F > W > B > Be
and if inertia is more time will be more..
So the answers will be...
1.Less
2.Less
3.Greater
4.Greater
5.Less
6.Less
