Question

The position of a particle s given by x=3-2t+3t^2. What is its instantaneous velocity and instantaneous acceleration as t=3.

At what time is the particle at rest

Answer 1

Step-by-step explanation:

velocity = dx/dt

`(dx)/(dt) = 6t - 2 = 16`

acceleration =

`\frac{ {d}^(2)x }{d {t}^(2) } = 6 \ \\`
