Algebra II Physics

1.     Explain the activity (3 points)

2.    Went outside and i had a golfball i started at a hight of one meter an tossed a golfball one time straight ahead an the second time up into the air. (one meter = three feet)

     

     Write the general equation for a projectile that is given above (1 pt)

3.     h=-16t^2 + v₀t + h₀

     

     Find the initial velocity for YOUR two throws (4 pts)

4.    first throw= 11.49    second throw= 13.58

     

     Write the general quadratic equation filling in the initial velocity and height. You should have two. (2 points)

5.    0=-16(.92)^2+11.49+3           0=-16(1.24)^2+13.58+3

     

     Find the time at which the item reached its highest point for each equation. EXPLAIN HOW YOU FOUND IT. (Round to the nearest tenth.) (5 pts)

6.    Time= .35    Time= .42

     

     Find how high the object went. (Round to the nearest tenth.) EXPLAIN HOW YOU FOUND IT. (5 points

       hight= 5.06  hight= 5
