Suppose David Ortiz hits a home run which travels 361. feet (110. m). Assuming it left the bat at 50.°, how fast was it hit?

  • physics - ,

    separate the initial velocity into vertical and horizontal components.

    Viv=Vsin50
    Vih=Vcos50
    horizontaldistance=Vih*t
    solve for t.
    Now,
    you know the vertical distance..
    Hf=Hi+Viv*t-1/2 g t^2
    where Viv=Vsin50
    solve for V.
