Question: A) A projectile is fired with an initial speed vo at an angle with respect to the horizontal. Neglect air resistance and derive a formula

A) A projectile is fired with an initial speed vo at an angle θ with respect to the horizontal. Neglect air resistance and derive a formula for the horizontal range R, of the projectile. (Your formula should make no explicit reference to time, t) at what angle is the range a maximum?
B) If v0 = 30km / hour and θ = 15o calculate the numerical value of R.
