1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. Find the speed of the particle

Respuesta :

Answer:

[tex]v(t) = 2t - 5[/tex]

Step-by-step explanation:

Given

[tex]s(t) = t^2 - 5t + 1[/tex]

Required

The speed of the particle

To do this, we simply differentiate the position function

i.e.

[tex]v(t) = s'(t)[/tex]

So, we have:

[tex]s(t) = t^2 - 5t + 1[/tex]

Differentiate

[tex]s'(t) = 2t - 5 + 0[/tex]

[tex]s'(t) = 2t - 5[/tex]

So, the speed function is:

[tex]v(t) = 2t - 5[/tex]
