An object is moving in a straight line with a constant acceleration initially it is traveling at 16 meters per second. 3 seconds later it is traveling at 10 meters per second. a) how far does it move during this time? b) how far does it move during half the time?

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?
