If you throw a cricket ball up into the air and the ball leaves your hand at 1.8m and travel with a speed of 9.7m s. What is the speed at the point it hits the floor. Accerlation due to gravity is 9.8 ms no air resistance

  • Physics -

    No matter what angle you throw it at, the kinetic energy increases by
    M g *1.8 m when it hits the ground. That means
    (M/2)(V2^2 - V1^2) = M*g*1.8
    Note that the mass M cancels.
    V2^2 = 2*g*1.8m + V1^2
    = 37.04 m^2/s^2 + V1^2
    = 37.04 + 94.1

    Solve for V1
