If 0.057Kg of ice at 0°C is added to 0.3Kg of water at 25°C in a 0.1Kg aluminum calorimeter cup. What is the final temperature of water?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
