someone can answer ????

Answer 1

question please

Answer 2

Help!!!!!!!!!!!!!!

Answer 3

Happen to have an English translation? I think it's asking about the magnitude of one of the vectors at t = 2s, but I'm not sure.

Answer 4

If that's the case, we simply plug in 2 for t, and evaluate each component.

To find the magnitude, we use:
\[|\vec{V}| = \sqrt{\vec{V}\cdot\vec{V}} = \sqrt{V_x^2 + V_y^2 + V_z^2}\]

Answer 5

I can not get the answer you found hits with some of these attached?

Answer 6

The module position vector t = 2 s the moment it (in meters):

Answer 7

The position of a moving vector is described by the equation: v (t) = 2ti + 3j ^ 4t Knowing the initial instant is given by the velocity v0 (t) = 3ti+2t^2j
The module position vector t = 2 s the moment it (in meters):????????????
