Asked Feb 6, 2019

The position of a particle moving along the x-axis is given by x = (21+22t-6.0t^2)m, where t is in s. What is the average velocity during the time interval t = 1.0s to t = 3.0s ?


Expert Answer

Step 1

At t1 = 1.0s, the position x1 is,

Step 2

At t2 = 3.0s, the position x2 is,

Step 3

Average velocity of the particle ...
