At one instant a bicyclist is 45.0 m due east of a park's flagpole, going due south with a speed of 14.0 m/s. Then 32.0 s later, the cyclist is 45.0 m due north of the flagpole, going due east with a speed of 14.0 m/s. For the cyclist in this 32.0 s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and (f) direction of the average acceleration? (Give all directions as positive angles relative to due east, where positive is measured going counterclockwise.)

A 379-kg boat is sailing 11.0° north of east at a speed of 1.80 m/s. 35.0 s later, it is sailing 38.0° north of east at a speed of 4.30 m/s. During this time, three forces act on the boat: a 32.1-N force directed 11.0° north of east (due to an auxiliary engine), a 21.8-N force directed 11.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
