a player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 28 m/s. what is the maximum height attained by the ball? Round the answer to the nearest tenth of a meter.

  • physics - ,

    Vo = 28m/s[30o].
    Yo = Vo*sin30 = 28*sin30 = 14 m/s.

    Y^2 = Yo^2 + 2g*h

  • physics - ,

    Vo = 28m/s[30o].
    Yo = Vo*sin30 = 28*sin30 = 14 m/s.

    Y^2 = Yo^2 + 2g*h
    h = (Y^2-Yo^2)/2g
    h = (0-(14)^2)/-19.6 = 10 m.
