Question 1035439: The velocity v of an object t seconds after it started from the origin is given by 3(v)=3t^2-6t-24.
1. Find the formula for the position.
2. Find the initial velocity.
3. When is the object at rest?
4. When does the object return to the origin.

.
The velocity v of an object t seconds after it started from the origin is given by 3(v)=3t^2-6t-24.

0.  Hence, the velocity is v = .   (1)


1.  Find the formula for the position.           s(t) =   (after integration (1) over t).
  
2.  Find the initial velocity.                   -8   ( substitute t = 0 into (1) )

3.  When is the object at rest?                  When  =    (when v(t) = 0.  Find the roots and take the positive root.)

4.  When does the object return to the origin.   When  = .   ( Solve it for t using factoring )
