1.	The shaft of a motor rotates at a constant speed of 1800 rpm. What is the angle in radians it has turned through in one second ?
Answer» SOLUTION : ANGLE it has turned in one rotation `=2pi` radian Number of ROTATIONS per second = `(18000)/60 = 300` RPS Angle through which the shaft turns in one second = `=300 xx 2pi = 600 pi` radian.
