A 50 kg kid swings on a swing with a length of 5 m. At the bottom, she has a velocity of 3 m/s. What is the force of tension in the swing at the bottom?

90 N
400 N
580 N
830 N

PLEASE HELP IM TAKING MY FINAL

Ireally just need to get finished with precal! i’m really sorry i have to do this! hope this !

The answer which is not a detail carson used to describe the pool in the cave at low tide is b.  hundreds of periwinkles browse the branches and roots of the trees. 

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
