Chapter , Problem 93

(choose chapter or problem)

Oasis A is 90 km due west of oasis B. A desert camel leaves A and takes 50 h to walk 75 km at \(37^{\circ}\) north of due east. Next it takes 35 h to walk 65 km due south. Then it rests for 5.0 h. What are the

(a) magnitude and

(b) direction of the camel’s displacement relative to A at the resting point? From the time the camel leaves A until the end of the rest period, what are the

(c) magnitude and

(d) direction of its average velocity and

(e) its average speed? The camel’s last drink was at A; it must be at B no more than 120 h later for its next drink. If it is to reach B just in time, what must be the

(f) magnitude and

(g) direction of its average velocity after the rest period?
