an exercise (in lbs) divided by the cross-sectional area of the tendon (in m) 8) If the initial position of an object is 3.9cm to the left of the origin and it moves in a straight line to a new position 12cm to the right of the origin in 2.7 seconds, what is the average velocity (in cm/s) at which the object moved along the line? Assume one-dimensional motion. Also assume the rightward direction is positive. A person leaves the starting line and runs a straight line down the track reaching a velocity of 7. roach 7.0 m/s velocity, what is the person's average
