3. A plane flying horizontally at an altitude of 1 mi and a speed of 500 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station.

1. A cannonball is launched at a 60.0° from the ground at 100.0 m/s. Calculate the maximum height achieved, the distance it traveled horizontally, and the time it took to travel its horizontal distance.

Starting from the relative position shown, aircraft B is to rendezvous with the refueling tanker A. If B is to arrive in close proximity to A in a 2.3-minute time interval, what absolute velocity vector should B acquire and maintain? The velocity of the tanker A is 306 mi/hr along the constant-altitude path shown. 8960 A 2710' В Answer: VB = ( i i+ i j) mi/hr

2. A child standing at a third story window (25 meters above the ground) throws a baseball at an angle of 30° above the horizontal with an initial velocity of 20 m/s. How far from the building does the ball hit the ground?

2. Peter is a pilot. He needs to deliver emergency supplies to a location that is 1000km away, N 30° W from his air base. The speed of the plane is set to I 600km/h. The wind velocity is 40km/h at 050°. Determine (i) the direction of the plane (ii) the magnitude of the ground velocity and (iii) Will Peter be able to make the delivery within 2 hours? Justify your responds.

A plane flies at an airspeed of 241 km/h. A wind is blowing at 78 km/h toward the direction 60° east of north. (a) In what direction should the plane head in order to fly due north relative to the ground?....................... ° west of north(b) What is the speed of the plane relative to the ground?........................ km/h

A plane flies directly West at a velocity of 250.km/hr if there is no wind.  What will be the plane’s resultant velocity to an observer on the  ground if the plane encounters a constant 40.0km/hr wind from the East ?

You are stationary on the ground and are watching a bird fly horizontally towards you at a rate of 1 m/s. The bird is located 20 m above your head. How fast does the angle of elevation of your head change when the horizontal distance between you and the bird is 50 m? (Leave your answer as an exact number.)

2. At an archery contest, a large circular target 5 ft in diameter is laid flat on the ground with the bull's- eye exactly 180 yd (540 ft) away from the archers. Marion draws her bow and shoots an arrow at an angle of 25° above horizontal with an initial velocity of 150 ft/sec (assume the archers are standing in a depression and the arrow is shot from ground level). a) What was the maximum height of the arrow? b) Does the arrow hit the target?

1. You are flying a helicopter 65 km due to Camp A. You then fly bearing 125 degree 89km to camp B. How far are you from the start?
