Calculate the range of the projectile using the initial speed and angle. Use g = 9.8m/s your calculation.
Initial speed is 18m/s
Angle is 75

Help please !!

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`
