An object starts from rest an accelerates at a constant rate in the +x direction and at some magnitude of velocity, in the +x direction, it has covered a displacement of 19 meters in the +x direction in a time of 2.6 seconds. a different object starts from rest and accelerates at a constant rate in the -x direction with a magnitude of acceleration equal to a factor 4 times less than the first object. when the second object reaches a magnitude of velocity which is a factor of 3 larger than the first objects, was is the magnitude of the second object's average velocity in m/s?
