Remember that w=mg where w is weight in Newtons, m is mass in kilograms, and g is gravity in
m/s2
. For example, for Earth, 445 N = 45.4 × 9.8
m/s2
:Notice that the x-axis values will be gravity in
m/s2
, which is already given in the table, and the y-axis values will be the weight in Newtons. Remember to round your weights to a whole number, and to enter the points starting with the lowest gravity (moon, then Mars, then Venus, then Earth).
Answer:
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

Kinetic energy = 1/2 mv^2
1/2 x 50 x 2.6^2
= 169J
