Question

(calculus !) The equation of the motion of a particle is s = 6t^2 + 5t + 2 where s is in meters and t is in seconds find the velocity as a function of t

Answer 1

The equation of motion is:

$s=6t^2+5t+2$

Recall that the velocity function v is given by:

$v=\frac{ds}{dt}$

Therefore,

$v=12t+5$

Therefore, the correct answer is choice B:

12t + 5
