Science Joke of the Day (Yes there actually are science jokes!)

Two molecules are walking down the street and they run in to each other.
One says to the other, "Are you all right?" "No, I lost an electron!" "Are you sure?" "I'm positive!

For those of you studying for the physics test

Here are some practice questions to help. Bring your results to me tomorrow at noon to see how you've done.

1) Floyd is in a really cool race car and is travelling at 28 m/s. How far will he travel in .75
   days ?

2) A boat load of Rivier girls are in a boat travelling at 12 m/s when one of them throws out
   the anchor. The drag of the anchor causes the boat to slow to 5.0 m/s in 15 seconds. How far
   did the travel during that time span ?

3) A child is at the top of a hill. He begins to roll down the hill and accelerates at 1.7 m/s2.
   There is a car parked 150 m at the bottom of the hill. If the car stays there for 12 seconds
   will the boy crash into the car ?


4) Two people are having a foot race. Person A starts the race with a running start running
   6.0 m/s. Runner B gets a 100.00 M head start and begins running from rest accelerating at
   .60 m/s2. If the race is 950 M in length who wins the race and by what distance ?
