Experiment by hanging your first object (object 1) on the hook. Hold on to the cardboard, and position the cardboard and string so the object dangles just off the edge of the table. Then let go of the cardboard. If it
moves, stop it when it reaches the edge of the table. Repeat the steps by replacing object 1 with object 2
on the hook. Finally, hang object 1 and object 2 together on the hook and repeat the steps. What do you
observe when you hang different objects from the hook? What happens when two or more objects are on
the hook together?

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
