1) The circular blade of a table saw is 30 cm in diameter and spins at 3600 rpm. a. How much time is required for one revolution? b. What is the acceleration of the teeth at the edge of the blade? 2) A plane attains a constant airspeed (speed of plane relative to air) of 400 km/ hr. The pilot sets out for a destination 800 km to the north but discovers that the plane must be headed 25.0 east of north to fly there directly. The plane arrives in 4.00 hr. Determine the wind velocity vector in magnitude-direction format
