An airplane with a speed of 52.6 m/s is climbing upward at anangle of 52° with respect to the horizontal. When the plane'saltitude is 760 m, the pilot releases a package.
(a) Calculate the distance along the ground, measured from apoint directly beneath the point of release, to where the packagehits the earth.
m
(b) Relative to the ground determine the angle of the velocityvector of the package just before impact.

A bird watcher meanders through the woods, walking 0.30 km dueeast, 0.70 km due south, and 2.10 km in a direction 38.0° north ofwest. The time required for this trip is 2.00 h.
(a) Determine the magnitude and direction (relative to due west)of the bird watcher's displacement. Use kilometers and hours fordistance and time, respectively.
| magnitude | Â Â km |
| direction |   ° north of west |
(b) Determine the magnitude and direction (relative to due west) ofthe bird watcher's average velocity.
| magnitude | Â Â km/hr |
| direction |   ° north of west |
