"VELOCITY and ACCELERATION versus DISTANCE in a STRAIGHT LINE. An object has an initial velocity VELINIT and is accelerated at a constant rate ACCELER to average velocity VELOAVE and travels DISTANCE in TIME. ------------- ACCELER │ OBJECT │ ----> straight line │ │ VELOCITY -----------> ------------- ----> | .......>.....>.......>.....| 0 DISTANCE Use these equations when acceleration, velocity and distance are important factors. A=accleration, V=final velocity at distance S, S=distance traveled at TIME. Enter at least two variables with nonzero values. For constant velocity, V=VELINIT. Type any key to exit. (c) Copyright PCSCC, Inc., 1993 *** Answer to problem *** Type ? then (esc) 0 (enter) to set all variables to zero. Set the distance S to1500 and the velocity V to 200. (a) An acceleration ACCELER=13.3 m/s^2 is neededand (b) the plane will takeoff in TIME=15 s. Type any key to exit. ||If A CD-10 jetplane needs at least a velocity of 200 m/s to take off from a 1500 m runway. (a) What must its acceleration be from rest and (b) how many seconds until takeoff at this acceleration? Type comma key to see answer. Type (F2) to return to helpfile."
