What is the magnitude of its average acceleration?(4.2ms-2) 3. An automobile is pes to the right along a straight highway, which we choose to be the positive x axis. Then the device driver puts on the brakes. If the pledge velocity (when the driver hits the brakes) is [pic], and it takes 5.0s to slow down to [pic], what was the cars average acceleration?(-2.0ms-2) 4.
