a ball is thrown at an initial angle of 37 and initail velocity of 23.0 m/s reaches a maximum height h, as shwon in the Figure. With what initial speed must a ball be thrown straight up to reach the same maximum height h?

  • physics -

    Vi^2=2gh

    Vi= sqrt (2gh)

  • physics -

    sin(37) * 23 = 13.8
