Is the dollar coin more or less dangerous than the penny, or is it the same? Put your answer and reason.

The dollar coin has more mass than the penny but they are moving at the same speed. The dollar coin might hurt more because it has more mass but it should be almost the same.

Great! I'm anxious to see the pictures when I get back on Thursday.


 * 1) __DROPPING TO SEE WHICH ONE HITS HARDER__
 * We Will be dropping them onto Styrofoam.
 * We will be dropping them from 4 meters (stairway)
 * We believe that we can hit the Styrofoam from that height.
 * We will know by the impact of the Styrofoam which one hit harder.
 * 1) We dropped the coins and it took 2.34 seconds. The impact on the syrofoam from the dollar coin was greater than impact of the penny. file:///var/folders/Z8/Z8jZXk+nH7mTyO11Eiam+FGftMw/-Tmp-/com.apple.PhotoBooth-T0x87101f0.tmp.e2XNMv/Photo%2029.jpg here is a picture of the impact of both coins. In the end our original idea that the dollar coin would have more impact than the penny was right.
