The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

The line OP is of constant length R. The angle θ = ω0t where ω0 is a constant.

(a) Use the relations

to determine the velocity of point P relative to O.

---

(b) Use Eq. (13.33) to determine the velocity of point P relative to O, and confirm that your result agrees with the result of part (a).

Strategy: In part (b), write the position vector of P relative to O as r = Re. where e is a unit vector that points from O toward P.
