A projectile is fired with an initial speed of vo = 6 0 m / s at = 3 0 o above

A projectile is fired with an initial speed of vo $=60$ m$/$s at  θ $=30$^o above the horizontal, as shown below. what is the maximum range $($R$)$ moved by the projectile along the x $-$axis.

Vosing 60 m/s 0=30 o cose R- 7
