The quantity that has units kg m2/sec2 is known as a

Energy

Explanation:

The unit is .

We can see the formula of kinetic energy is

Where is the mass and is the velocity of the object.

Which means its unit would be kg times square of meter per second, that is  . Which is often referred as Joule.

Also, when look at the formula of work done by an object.

Where is the force and is the distance traveled by the object due to force .

We an see that its unit is kg meter per second squared times meter. That is equivalent to . This is also a type of energy.

So, the unit is the unit of energy.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the answer is 12 as i may remember
