Question

this is my 5th time waisting my points for this question because I could fail my final and I am not getting any answers so can someone give me some attention here!!!

Answer 1

The person needs to apply 25 N to balance the seesaw

Step-by-step explanation:

Moment

The moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.

The moment M of a force F located at a distance x from the axis of rotation is calculated as follows:

M = F.x

The image shows a moment of M=100 N.m is needed to be applied to balance the seesaw. It can also be noted that the distance to the pivot is x=4 m

To calculate the force needed to balance the seesaw, we solve for F:

`\displaystyle F=(M)/(x)`

`\displaystyle F=(100\ N.m)/(4\ m)`

F = 25 N

The person needs to apply 25 N to balance the seesaw
