Question #f736b

Answer 1

The equation for instantaneous velocity at a time `t` is the first derivative of position.

Explanation:

I am assuming the question is asking about the general concept of velocity for any moving object, as opposed to for a specific situation.

If a function `vecx(t)` describes an object's position at any time `t`, then the velocity will be the first derivative of `vecx(t)` with respect to time:
`vecv(t) = d/dt vecx(t)`
