Answer:
acceleration = 1.79 m/s^2
Tension = 6817 N
Explanation:
First let's find Elizabeth's weight:
Her weight is greater than the normal force (N = 450 N), so the elevator is going downwards.
The acceleration of Elizabeth is given by:
Where P is the weight of Elisabeth, N is her normal force, m is her mass and a is the acceleration. Then, we have that:
The tension in the cable is given by:
In this case, we use the total mass, so we have:

No, because if the net force were 0, it would either be at rest or moving in constant velocity.

Answer:
30000 J = 30 kJ
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = 
So you get,
K.E. = 
= 30000 J = 30 kJ
