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?
A spherical Balloon is inflated at the rate of 144pie cubic inches per minute (in^3/min). How fast is the radius of the balloon changing when the radius is 4 inches? Recall the formula for volume of sphere: V(4/3) pieR^3?
An unmarked police car travelling a constant 80 km/h is passed by the speeder travelling 100 km/h. precisely l.0s after the speeder passes, the policeman steps on an accelerator; if the police car's acceleration is 2.0m/s2, how much time passes befor..
