38. During takeoff, an airplane climbs with a speed of 180 m/s at an angle of 34° above the horizontal. The speed and direction of the airplane constitute a vector quantity known as the velocity. The sun is shining directly overhead. How fast is the shadow of the plane moving along the ground? (That is, what is the magnitude of the horizontal component of the plane's velocity?)

2. A migrating Canadian goose is flying south for the winter. It can fly 100 miles due south in 4.3 hours in calm air. During that time a strong westerly wind is blowing at 10 mph. How much has the wind blown it off its southerly course during its 100 mile trip if it continues to fly aiming due south ? Distance off course = miles
A train moves south at a speed of 30m/s relative to the ground in a rainy weather with wind blowing southward . Each raindrop makes a 70 degree angle with the vertial according to an observer on the ground. However, an observer on the train sees raindrops falling to the ground in a vertical direction. Find a vector expression for the velocity of raindrops relative to the ground.

1. An archer shots an arrow with an initial speed of 60.0 m/s at an angle of 30.0° with the archer's hand and the horizontal. If the archer is standing from the edge of 90.0 m tall building, then strikes a target on the ground. Note: The distance of the archer's hand with respect to the edge of the building is 5.0m. Neglect air resistance. Let the archer's hand be y=0. Find: a. The time taken by the arrow to hit the target at the ground level. b. The distance of the target from the base of the tall building. c. The maximum height reached by the arrow with respect to the archer's hand. d. The horizontal and the vertical component of the arrow's velocity just as it strike the target. e.

Geese migrate along north and south directions for well over a thousand kilometers in some cases traveling speeds up to about 100 km/h. If one such bird is flying at 100km/h relative to the air but there is a 34.0 km/h wind blowing from the west to east. A.) at what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? Express answer in degrees b.) how long will it take the bird to cover a ground distance of 500 km from north to south? ( Note: Even on cloudy nights many birds navigate using the earth's magnetic field to fix the north-south direction)
