Arectangular trough, 2.0 m long, 0.70 m wide, and 0.45 m deep, is completely full of water. one end of the trough has a small drain plug right at the bottom edge. part a when you pull the plug, at what speed does water emerge from the hole? express your answer using two significant figures.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
