  1. Step 1: find the time it takes for gravity to pull the cat 10m to the ground.  

    Acceleration due to gravity: 9.8 meters/second/second.  

    For this problem I'll round it off to10 m/s/s.  (This, you should have memorized).

    Basic formula:

    x = 1/2 * a * t^2

    (this you can look up or memorize for your tests)

    10 = 1/2 * 10 * t^2

    2 = t^2

    1.414 = t

    So, it takes 1.4 seconds to reach the ground.

    Step 2: multiply the time by the horizontal velocity

    1.4 * 5 = 7 meters.

    (Step 3: Multiply the distance * $100 to determine the veteranarian bill for the severely wounded cat.  Poor kitty!)

    .


  2. Its hard to tell by the info given.

  3. jumps in which direction?

  4. you cannot calculate from the information given

  5. it all depends how hard it pushed itself away from the building, if it had legs as strong as supermans, it could land hundreds of miles away.

    you forgot a vital piece of info.
