1. An object is originally moving in the +x direction at 16 m/s and a constant acceleration is applied to it. When it is at a displacement of 7 meters in the +x direction it is moving in the -x direction at 6 m/s. What is the acceleration of the object in m/s2? If in the -x direction, include a negative sign. 2. An object travels in the +x direction for 6 meters for 3.4 seconds and then, immediately, changes...

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...

A car is initially moving at 9.9 m/s in the positive x direction and accelerates at a constant acceleration of 3.4 m/s2 in the positive x direction for 6 seconds. It then immediately has an acceleration of 6.6 m/s2 in the negative x direction. After some time, its velocity is 27.6 m/s in the negative x direction. What is the average velocity for the entire trip in m/s? Indicate the negative x direction by including a negative sign but do...
