The friction in its bearings is so small that it can be ignored. A sandbag of mass m is dropped onto the merry-go-round, at a position designated by T. The sandbag does not slip or roll upon contact with the merry-go-round 0 Part A Rank the following different combinations of m and r on the basis of the angular speed of the me rry-go-round after the sandbag "sticks" to the merry-go-round Rank from largest to smallest. To rank items as equivalent, overlap thenm m-10 kg r 0.50R m-10 kg r 0.25R m-20 kg r 0.25R m = 15 kg r = 0.75 R m 10 kg r = 1.0 R r 0.25 R

Explanation / Answer

The samd bag increases the moment of inertia. Thusa, there will be a decrease in final angular velocity. Larger the moment of inertia smaller will be the angular velocity.

1) 2.5R2 2) 0.625 R2    3)  1.25 R2 4)  8.4375 R2 5) 10R2 6) 2.5R2

Basing on the angular speed 2,3,1=6,4,5
