Physics Blog 6

When I was on the computer last night, I accidentally hit my water bottle down.   The water got on my keyboard and mouse so I went to get a paper towel and absorb the water.  As I was doing this, I noticed that my hand and the water bottle created a sticky collision which moved the water bottle off the table.  Gravity then took control and tipped the bottle over and water spilled out.  Sticky collisions are m1v1+m2v2= (m1+m2)vf so we can find final velocity from our givens.  My hand was moving at around 4.2672 m / s and has a mass of about 1.81436948 kilograms.  The water bottle, which was half full had about 191.722284 grams or .191722284 kilograms. It's initial velocity was 0. Vf= (m1v1+m2v2)/ (m1+m2).  (1.81436948* 4.2672+.191722284*0) /2.00609176= 3.8593835 m/s.

  6. You should really drink water from the faucet instead of creating plastic waste.
