Answer:
Step-by-step explanation:
The velocity is the derivative of the position.
The acceleration is the derivative of the velocity.
In this problem, we have that:
Looking at the derivative table, the derivative of 
is 
and the derivative of a constant is 0.
So:
Your answers are correct.
Answer:
They are not.
Step-by-step explanation:
Let's solve it and see:
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5, 1.
