A stone thrown off a bridge 20 m above a river has an initial velocity of 12 m/s at an angle of 450 above the horizontal.
a. What is the range of the stone?
b. At what velocity does the stone strike the water?
(magnitude and direction)

  • physics -

    break the initial velocity into horizontal and vertical components.

    In the vertical:
    -20=0+Vvi*t-4.9t^2
    solve for t.
    Range: Vhi*t
