Two children are sitting on opposite ends of a seesaw of negligible mass. of 40 kg child is 2.0 m from the pivot point, how far from the pivot point will the other 30 kg child sit on the seesaw to be at equilibrium?

Distance of the second child from the pivot point will be 2.66 m

Explanation:

We have given mass of the first child

Distance from the pivot point

Mass of the second child

We have to find the distance of the second child from the pivot point

For this we have to balance the moment

So

So the distance of the second child from the pivot point point will be 2.66 m

what question you dont ask a question

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
