An object is moving forward along a straight line. The distance the object travels (in meters) from its starting position t seconds after it started moving is given by �(�) = 3√�. Determine the average velocity of the object over the interval from t=1 to t=4.

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
