Question

The top ball is Fred's, the second is Betty's, the third is Barney, and the forth is Wilma's.

Fred's ball and Barney's ball have the same size, but Barney's ball is hollow. Betty's ball and Wilma's ball are scaled down versions of Fred's ball and Barney's ball respectively. They all place their bowling balls on the same pitch incline and release them from rest at the same time. (Select G-Greater than, L-Less than, E-Equal to, ). Please see diagram printed on your homework page. The order of the objects in the diagram is Fred, Betty, Barney, Wilma. A) The time it takes for Wilma's ball to hit the pins is. hat for Betty's ball to hit B) The time it takes for Barney's ball to hit the pins is that for Fred's ball to hit. C) The time it takes for Fred's ball to hit the pins is. that for Wilma's ball to hit. D) The time it takes for Barney's ball to hit the pins is that for Bctty's ball to hit. E) The time it takes for Fred's ball to hit the pins is.. that for Betty's ball to hit. F) The time it takes for Wilma's ball to hit the pins is hat for Barney's ball to hit. ns 1S

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.greater
2.less
3.greater
4.Greater
5.greater
6.Greater
