You have 1.60 kg of water at 27.0°C in an insulated container of negligible mass. You add 0.640 kg of ice that is initially at -22.6°C. Assume no heat is lost to the surroundings and the mixture eventually reaches thermal equilibrium. If all of the ice has melted, what is the final temperature (in °C, round to 2 decimal places) of the water in the container? Otherwise if some ice remains, what is the mass of ice (in kg, round...

A m1 = 15.4 kg mass and a m2 = 11.7 kg mass are suspended by a pulley that has a radius of R = 10.3 cm and a mass of M = 2.84 kg. The cord has a negligible mass and causes the pulley to rotate without slipping. The pulley rotates without friction. The masses start from rest d = 2.72 m apart. Treating the pulley as a uniform disk, determine the speeds of the two masses as they...
