A spacecraft headed to Mars has fired its engines and accelerated from rest until has escaped Earth's gravity. The spacecraft
reaches a planned speed and then turns the engines off. At this point, in space, which graph bests represents the motion of the
spacecraft?

Which of the following statement is false

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

Based on this activity, is kinetic energy always transformed into potential energy?
