On landing, the plane touches the runway with a speed of 65 m/s. the figure shows the speed of the plane after 1 second. calculate the acceleration of the plane during its landing speeds: (in order) 8 m/s, 16 m/s, 24 m/s, 65 m/s , 60 m/s
time: (in order) 0.0s , 1.0s, 2.0s, 3.0, 0.0s, 1.0s,

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?
