Gibbons, small asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. a 9.3 kg gibbon has an arm length (hand to shoulder) of 0.60 m. we can model its motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. at the lowest point of its swing, the gibbon is moving at 3.4 m/s . what upward force must a branch provide to support the swinging gibbon? express your answer to two significant figures and include the appropriate units.

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Well i am not very good at this but  i would be guessing 1hope i
