In middle ages people believed that abnormal behavior was cause by ? a-pysic function of the brain b-imbalance of fluids c-demonic possession d-genetic influence

C, they didn't know any better

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

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:
