Answer #1

And: (4) Any of the previous answers is possible.

The accelerations in the x and y directions are completely independent of each other. So having zero acceleration along the x axis cannot decide what the acceleration will be along the y axis.

    An object is originally moving at 3.5 m/s in the negative x direction with a constant acceleration of 2.4 m/s2 in the negative x direction for 5.1 seconds. Then (immediately) a constant acceleration is applied to in the positive x direction. After some time, the average velocity for the entire trip is 0 m/s., and at that time, the object is moving at 61.2 m/s in the positive x direction. How long was the acceleration applied in the positive x...
