At a particular location, a hurricane's eye is moving with speed 40.8 km/h and in the direction 31.0° north of west. The hurricane keeps going at this velocity for 2.90 h, then changes direction, and heads due north. When its direction changes, it slows down to 22.6 km/h. It travels at this new velocity for 1.50 h. (Let î represent east and ĵ represent north.) Required:
a. Write the hurricane's initial velocity (in km/h).
b. Write the hurricane's final velocity (in km/h) in unit-vector notation.
c. Write the hurricane's displacement (in km) during the first 3.50 hours.
