cannonball

Shoot the red ball with a humanoid cannonball.

用类似人形的炮弹射击红色的求。

There are exceptions to this rule: The cannonball jellyfish—a seafood delicacy in Asia—shoots through the water at 15 centimeters per second, a decent clip.

当然也有例外，比如亚洲的一种美味海鲜“炮弹水母”，就能以每秒15厘米的速度在水中穿梭，看起来像把水流剪开一样。

Look at picture of cannonball flight and you will see they will describe it like this , as though at the end of the flight its dropping almost vertically.

仔细看下炮弹的飞行路线,你会发现它们是这样运动的，但是炮弹在最后的落地阶段几乎是垂直的。
