note that a y = 0 so that there is no ambiguity denoting a x simply as a . We choose + x to the right and + y up. We also note that the x component of the rope’s tension (acting on the crate) is F x = F cos θ = (450 N) cos 38° = 355 N, and the resistive force (pointing in the – x direction) has magnitude f = 125 N. (a) Newton’s second law leads to 2 355 N 125 N 0.74m/s . 310 kg x Ffm a a −= ¡ ==
