Q. A man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of the man and chair is 86.0 kg. With what force magnitude must the man pull on the rope if he is to rise with upward acceleration of 1.43 m/s2?

Q. An open container holds ice of mass 0.600 at a temperature of -13.7. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 710 .

The specific heat of ice to is 2100 and the heat of fusion for ice is . How much time passes before the ice starts to melt? From the time when the heating begins, how much time does it take before the temperature begins to rise above 0?
