The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

For astronaut training, die airplane shown is to achieve “weightlessness” for a short period of time by flying along a path such that its acceleration is ax = 0 and ay = –g. If the velocity of the plane at O at time t = 0 is v = v0i, show that the autopilot must fly the airplane so that its tangential component of acceleration as a function of time is
