[单选题]
A projectile is launched with an initia 3ywo6m o3c7bml veloclxc,; *x6ov lg, i94kg gt6obkity of $60.0 \; m/s$ at an angle of $30.0^{\circ}$ above the horizontal. How far does it travel?
A. $143.2 \; m$
B. $190.9 \; m$
C. $238.6 \; m$
D. $318.1 \; m$
E. $381.8 \; m$
参考答案: D
本题详细解析:
If the initial velocs15 hf ekxv(l 8dj+1cmity is $x$ and the launching angle is $y$, the formula to calculate it is $x^2*sin(2*y/180*pi)/9.8$
