At the winter design condition, the output capacity of a fossil fuel warm air furnace should not be less than the calculated total heating load. Nor should it exceed the design heating load by more than __________

A 0.50-kg mass is attached to a light string and moves in a circle of radius 0.80 m on a frictionless horizontal surface with an angular speed of 2.0 rad/s. The string is slowly pulled inward so that the radius decreases to 0.40 m. What is the new angular speed of the mass? (I = mr^2)

A 0.50-kg block is placed against a horizontal spring with a spring constant of 400 N/m on a frictionless surface. The spring is compressed 0.20 m and then released. (a) What is the elastic potential energy stored in the spring? (b) What is the speed of the block when it leaves the spring? SHOW WORK.
