A dumbbell-shaped object is composed by two equal masses, m, connected by a rod of negligible mass and length r. If Iâ is the moment of inertia of this object with respect to an axis passing through the center of the rod and perpendicular to it and Iâ is the moment of inertia with respect to an axis passing through one of the masses we can say that .
a. lâ = lâ.
b. lâ > lâ.
c. lâ > lâ

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
