a particle moves along of the x_axis according to the equation X=2t+3t^2, whare x is in m and t is in second. calcualt the instantaneous velocity and the instantaneous acceleration in t=3s​

Instantaneous velocity   meter per second

Instantaneous acceleration   meter per second square

Explanation:

Given equation of distance X =

Instantaneous velocity  

Substituting the value of t = 3 seconds, we get -

meter per second

Instantaneous acceleration     meter per second square
