A wooden rod of negligible mass and length 80.0cm is pivoted about a horizontal axis through its center. A white rat with mass 0.450kg clings to one end of the stick, and a mouse with mass 0.220kg clings to the other end. The system is released from rest with the rod horizontal

Part A
If the animals can manage to hold on, what are their speeds as the rod swings through a vertical position?
Take free fall acceleration to be 9.80m/s2 .

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
