Answer:
1) s(3) = -32 feet.
2)v(5) = 3 feet/sec
3)a(4) = 12
4) Velocity becomes zero at t = 5 seconds
Explanation:
Given that position as a function of time is

Now by definition of velocity we have

Now by definition of acceleration we have

Applying values of time in corresponding equations we get
1) s(3)=
2)v(5)=
3)a(4)=
4)To obatin the time at which velocity is zero equate the velocity function with zero we get

Thus the correct time is 5 seconds at which velocity becomes zero.
