Math Problem Statement
You enter an antique classic car road rally with your 1956 Studebaker Golden Hawk. The rally course consists of the following segments: travel north at 28.0 m/s for 30.0 min, then east at 36.0 m/s for 40.0 min, and finally northeast at 39.0 m/s for 50.0 min. For the entire trip, determine the following. (a) displacement vector (magnitude and direction) and distance traveled displacement vector magnitude m displacement vector direction ° North of East distance m
(b) average velocity vector (magnitude and direction) and average speed average velocity vector magnitude m/s average velocity vector direction ° North of East average speed m/s
