"A child and her father are playing on a seesaw. They are exactly balanced when the girl (mass 46 kg) sits at the end of the seesaw, 2.75m from the pivot. If her father weighs 824 N, how far is he from the pivot?"
(sum of) clockwise moment(s) = (sum of) anticlockwise moment(s)
moment (Nm) = force (N) * perpendicular distance from pivot to line of action of the force (m)
The Attempt at a Solution
girl is mass 46kg (kilograms) whilst her father has weight 824 N (newtons)?!
46 x 2.75 = y x 824
126.5 = 6.51 * 824
y = 6.51?
= 6.51 metres from pivot?
