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
9) Generic Villain, in an airplane, is chasing Generic Hero who is driving a car. The speed of the airplane is 147 m/s and the speed of the car is 51.0 m/s. If the Villain, at an altitude of 1.00E2 m, wants to drop a bomb on the Hero (and assuming the airplane is in level flight) how far should they be away from the car when they do so? (If you care, the hero gets away with some generic special effects and, you know, turning...) (434 m)
At a long distance shooting match, a bullet is fired with a muzzle velocity of 3000 feet per second from a rifle held in the horizontal position. When fired the sights of the rifle was dead center of a target. The bullet strikes the target at 4.00 ft below the center of the target. How long (in seconds) did it take for the bullet to reach the target? How far away (in unit of yards) was the target? Neglect any air resistance to the bullet. Make a simple sketch. Make a list of all given values, units, and the variables they represent. write the general form of the equation you are going to use. Insert the known values and solve. For problems with vertical motion State at the start of the problem which direction is positive by using an up or down arrow. Keep the velocity components and time to 2 decimal places

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 ?
A fireworks show is choreographed to have two shells cross paths at a height of 151 feet and explode at an apex of 189 feet under normal weather conditions. The shells have a launch angle 0= 70° above the horizontal. If a strong wind induces a constant rightward acceleration of 16 ft/sec² for the fireworks shells, determine the horizontal shift Ax of the crossing point of the shells.
