Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?

prisoha [69]

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

$\Rightarrow F>10\ N$

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

The un-factored version is x^2+4x-12

-b/2a=x
