Question

1. Convert (a) 50 rev to radians, (b) 48π rad to revolutions, (c) 7200 rpm to rad/s, (d) 22 rad/s to rpm, (e) 2 rad/s to deg/s.

Answer 1

(a) $50$ $rev=$ $314.16$ $rad$

(b) $48\pi$ $rad$ $=$ $24$ $rev$

(c) $7200$ $rpm$ $=$$754$ $rad/s$

(d) $22$ $rad/s$ $=$ $210$ $rpm$

(e) $2$ $rad/s$ $=$ $114.59$ $deg/s$
