- A Lockheed Martin F-35 II lighting jet takes off from an aircraft carrier with a runway length of 90 m and a takeoff speed 70 m/s at the end of the runway. Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35’s acceleration decreases to a constant acceleration of 5.0m/s2 at 30 with respect to the horizontal. (a) What is the initial acceleration of the F-35 on the deck of the aircraft carrier to make it airborne? (b) Write the position and velocity of the F-35 in unit vector notation from the point it leaves the deck of the aircraft carrier. (c) At what altitude is the fighter 5.0 s after it leaves the deck of the aircraft carrier? (d) What is its velocity and speed at this time? (e) How far has it traveled horizontally?Position, Displacement, and Average Velocity Consider a coordinate system in which the positive x axis is directed upward vertically.

- A Wide Reciever is running along the sideline straight towards the goal at a constant speed. When he is 27 m away from the goal line he cathces the ball, but theire is a cornerback 12 m behind him moving with a connstant speed of vc=9.0 m/s what speed should the wide reveiver have to make sure he reaches the goal line just as the cornerback reaches him.Two ducks, Donald and Cassiopeia, are gliding gracefully toward eachother along a pond, in a straight line. Donald is initially moving at v =0.500 m/s, and begins accelerating at 0.100 m/s2 at t = 0 s. Cassiopeiamoves at a constant speed of v = 0.700 m/s. If they are initially separatedby 25.0 m, where will they collide? Take Donald’s initial position as theorigin. How long will it take for them to collide?The position of a particle along a straight-line path is defined by s = (t3 - 6t2 - 15t + 7) ft, where t is in seconds.
