The velocity as a function of time is given as v(t) = 6t−t2 in m/s and t in seconds (s). Consider the time interval from t=0 tot = 12

A:Find the time after t=0 when the particle changes direction.

B:Find the time before which the acceleration is positive.

C:What is the displacement of the object in the time interval given above?

Step 1

Given:

Step 2

Part (a): at time after t=0 when the particle changes direction, its velocity at that time become zero

Step 3

Part (b): time before which the acceleration is positive implies that ac...
