February 5 at 10:00 PM Average Velocity 1) An object is moving along the x axis. At t 5.8 s, the object is at x 3.0 m and has a velocity of -4.2 m/s. At t 7.1 s, it is at x .9.0 m and its velocity is -1.0 m/s. Find the average acceleration between t a 5.8 s and t 7.1 s. m/s2 Submit copyright o 2017 Freeman worth Publishers a division of Maanillan Leaming, About l Tech Support l Find Your Local Sales Rep I Terms of Use I Privacy Policy

Explanation / Answer

Average acceleration = change in velocity/elapsed time

= (-1.0 - 4.2)/(7.1-5.8) = -4 m/s2

In our case, the object encounters a deceleration of -4m/s2
