Q. A 240 , 50.0-cm-diameter turntable rotates on frictionless bearings at 57.0 . A 22.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along a frictionless groove in the surface of the turntable. What is the turntable's rotation angular velocity when the block reaches the outer edge?

Q. A small immersion heater is rated at 373 W. Estimate how long it will take to heat a cup of soup (assume this is 250 mL of water) from 20°C to 50°C.
