A Cessna Citation II jet (call number 90-RC) has a lift-off velocity of 260 km/hr. The runway that 90-RC takes off from is 1200 m long. (a) What is the minimum acceleration that the jet has to have in order to take off before it reaches the end of the runway? (b) How long does it take for 90-RC to take off? (c) 20 s into the takeoff, a fault occurs in one of the engines. From this point on, what acceleration does the jet need in order to stop before it reaches the end of the runway?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
