# Physics' Quesion

Pulling a Crate A worker drags a crate across a factory floor by pulling on a rope tied to the crate (Fig. 6-60). The worker exerts a force of 450 N on the rope, which is inclined at 38° to the horizontal, and the floor exerts a horizontal force of 125 N that opposes the motion.

Figure 6-60 (image is in this link http://www.webassign.net/hrw/05_44.gif )

(a) Calculate the magnitude of the acceleration of the crate if its mass is 315 kg.

(b) Calculate the acceleration if the crate's weight is 315 N.
