Calculate the range (using g=9.8m/s) and the height of the pumpkin using the initial speed ( 18m/s), half-time (1.7) and angle (75).

    There's a problem similar to this. I'll just repost it here:

    Range of projectile formula:
    R = vo^2 sin(2θ) / g
    where
    θ = angle
    vo - initial velocity
    g = acceleration due to gravity = 9.8 m/s^2

    substitute the values to get the range:
    R = (18^2) * sin(2*75°) / 9.8
    R = ?

    Make sure your calculator is in Degrees mode, not Radians mode.
    Hope this helps~ `u`
