Calculate the range (using g=9.8m/s) and the height of the pumpkin using the initial speed ( 18m/s), halftime (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`
