As illustrated, a peg P is constrained to slide within both a smooth horizontal chute and the slotted link OQ, which is free to rotate about its pivot O with an angular speed and acceleration of ω and α, respectively. At a particular instant, the peg is a distance rP/O = 0.84 m form the pivot O, and the link is angled at θ = 63 degrees with respect to the horizontal. If the peg's velocity in the chute is a constant vP = 5.4i m/s, what is the b1 component of arel? Specify your answer in m/s^2 to 1 decimal place.
