- Part of the challenge is speed, too, how quickly you can get these answers in terms of getting them in on time.

部分困难也会来自于速度，你多快能做出答案,能否在规定的时间做完。

The beat will do--control--that, so it's the pace or speed of the beat.

节拍才是根本,所以速度指节拍的快慢

If you want to find the speed there, you put the equation v^=v0^-2g.

如果你想求出那一点的速度,可利用方程v^=v0^-2g

So, we can just plug it in. Speed is equal to the distance traveled, which is lambda over the time elapsed, which is 1 over nu. so, we can re-write that as speed is equal to lambda nu times nu, and it turns out typically this is reported in meters per second or nanometers per second.

经过的距离和所花的时间,我们把它们带进来,速度等于经过的距离,也即是lambda除以,所花的时间,通常它的单位,是米每秒或者纳米每秒。
