On takeoff, an airplane climbs with a speed of 183 m/s at an angle of 32.5° 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?)

The New Hampshire State Police use aircraft to enforce highway speed limits. Suppose that one of the airplanes has a speed of 130 mi/h in still air. It is flying straight north so that it is at all times directly above a north–south highway. A ground observer tells the pilot by radio that a 60.0 mi/h wind is blowing but neglects to give the wind direction. The pilot observes that in spite of the wind the plane can travel 130...

The pilot of a light plane heads due North at an airspeed of 240 km/h. A wind is blowing 90 km/h at an angle of 30 degrees E of N relative to the ground. A) What is the plane’s velocity with respect to the ground (give both magnitude and direction) if the pilot does not correct her course? B) In order to fly north (relative to the ground) , the pilot must fly into the wind at some angle. If...

A 250-m-wide river flows due east at a uniform speed of 2.8m/s. A boat with a speed of 7.7m/s relative to the water leaves the south bank pointed in a direction 31o west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west.

for this problem - draw the vector velocity triangle. Draw the ”east” vector first, then draw the ”north” vector. The ”magnitude of the velocity relative to Earth” will be the hypoteneuse of the triangle. For the angle, solve for the angle with respect to ”East”.¿¿ A ferry is crossing a river. The ferry is headed due north with a speed of 1.5 m/s relative to the water and the river’s velocity is 4.9 m/s to the east. a) What is...
