Which diagram best describes qualitatively the rockets trajectory from point A to point B?
The answer is B, and heres why Its not A, because the rocket does not change sideways direction, its constantly moving upwards It’s not C, because as the engine fires, it accelerates, diagram C will have you believe that it instantly has a constant velocity It’s not D because the rocket doesn’t stop moving sideways at any time It’s not E, because based on that diagram, it’s sideways motion is accelerating compared to the forward motion, which is not true without elimination, B makes sense logically at first the engine will barely move in the forward direction, hence giving it almost completely vertical motion, as the rocket’s thrust continues to fire, it will always accelerate, eventually surpassing the sideways speed until its net velocity is almost completely in the direction of the thruster motion
