Exercise 2: Vector Review and Time Deriviatives
1. Use the definition of vector product, a x b to find the unit vector perpendicular to a
and b. Let a = 3.0j 1.0k and b = 2.0i + 1.0j + 3.0k.
Exercise 1: Vector Review
1. A camel travels 22 km west and then 7.8
km southwest (45). What is the displacement
vector of the camel from the point of origin
(magnitude and direction). Draw a diagram.
|C| = 28.1 k
Exercise 3: Relative Motion
1. Huck Finn walks at a speed of 0.70 m/s across his raft (that is, he walks perpendicular
to the rafts motion relative to the shore). The raft is traveling down the Mis
