Answer: Greater than 10 N
Step-by-step explanation:
Given
Gravity force on metal is 10 N
But the metal piece is rising i.e. there must be an upward force greater than 10 N
Suppose the force is F
So, we can write
Any force greater than 10 N is sufficient for the metal to move upwards
The greater the amount of force faster will be the movement
For this case we have:
Be a function of the form
Where:
If we want to find f (-2), we substitute , then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:
