let me ask one thing

Haven't you ever been taught never use a very same term to represent completely things?

In that scenario, you firstly said the Vf was the final velocity, then at the same time you used the same Vf for something else totally different without saying anything. How can you expect people read your mind? Isn't it misleading?

• 別忙着下结论。车祸受伤是因为保险带没拉住人，气囊没挡住头，还是车身形变引起的？我看后者可能性大些。那样的话，经撞是很重要的。 -周老大- ♂ (0 bytes) () 10/07/2014 postreply 21:19:05
