Question

A heavy boy and a lightweight girl are balanced on a massless seesaw. if they both move forward so that they are one-half their original distance from the pivot point, what will happen to the seesaw? assume that both people are small enough compared to the length of the seesaw to be thought of as point masses.

Answer 1

the saw will tip towards the heavy boy. they are centered on the main pivot point so weight dosnt matter but as they go out. mass and weight will determin if the saw moves or not
