A 2.9 kg collar is free to slide on a rough rod rotating in the horizontal plane. The collar's radial position along the rod is governed by r(t) = (0.10+0.32et) m, and its angular position is described by θ(t) = ωt rad, where ω = 2.0 rad/s. What is the er component of the force acting on the collar at t = 1.4 s? Specify your answer in N to 2 decimal places.
