Q. A 65 meteorite buries itself 5.5 into soft mud. The force between the meteorite and the mud is given by = (660 ), where is the depth in the mud.
Q. A boy whirls a stone in a horizontal circle of radius 1.5 m and at height 1.7 m above ground level. The string breaks, and the stone flies horizontally and strikes the ground after traveling a horizontal distance of 10 m. What is the magnitude of the centripetal acceleration of the stone while in circular motion?
