In order to catch a ball, a baseball player naturally moves his or her hand backward in the direction of the ball's motion once the ball contacts the hand. this habit causes the force of impact on the players hand to be reduced in size principally because (consider the impulse-momentum theorem: f▲t = m ▲v .)
group of answer choices
the resulting impact velocity is lessened
the momentum change is decreased
the time of impact is increased
the time of impact is decreased

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
