A girl, who weighs 15N sits 4 m from the fulcrum of a seesaw. A boy, who weighs 20N, sits 2m from the fulcrum (the opposite side of the fulcrum relative to the girl) on the same seesaw. What is the magnitude and direction of the net torque on the seesaw.?

A heavy boy and a lightweight girl are balanced on a massless seesaw. If they both move forward so that they are one-third 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. A) Nothing will happen; the seesaw will still be balanced B) The side the girl is sitting on will tilt downward C) The...

A 32.0-kilogram child sits on a uniform seesaw of negligible mass; she is 2.10 m from the pivot point (or fulcrum). How far from the pivot point on the other side will her 22.0-kilogram playmate have to sit for the seesaw to be in equilibrium?

A girl slides down a snowy hill on an inflated tube sled where she collides with a boy who is stationary in another tube sled
A girl slides down a snowy hill on an inflated tube sled where she collides with a boy who is stationary in another tube sled. After the collision the girl moves off at an angle θ1 = 20 degrees from her original direction of motion and the boy moves off at an angle θ2 = 20 degrees, as shown in the figure, at half the girl's final speed. What is the ratio of the girl's mass to the boy's mass?

Suppose a 28.4-kg child sits 0.67 m to the left of center on the same seesaw as the problem you just solved in the PRACTICE IT section. A second child sits at the end on the opposite side, and the system is balanced. (a) Find the mass of the second child. 8.55 kg (b) Find the normal force acting at the pivot point. 362 Your answers to part (a) and (b) are not consistent....

Tarzan, who weighs 866 N, swings from a cliff at the end of a 16.0 m vine that hangs from a high tree limb and initially makes an angle of 24.3° with the vertical. Assume that an x axis points horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 789 N. Just then, what are (a) the force from the vine on Tarzan in...
