16. What force is needed to accelerate a 500 kg object at a rate of 10 m/s2?*
(3 Points)

Answer:
The second one
Explanation:
The formula to calculate force is:
F=m*a
So, 500 kg*10 m/s= 5000 N
The reason why it is not the last one is because we are looking for force, which is measured in Newton's.
I really hope this helps.
