A seconds pendulum is one that passes through its equilibrium position once every 1.000 s. Part A
What is the period of a seconds pendulum?
Express your answer to four significant figures and include the appropriate units.
Part B
A seconds pendulum in Chicago has a length of 0.9933 m. What is the acceleration due to gravity in Chicago?
Express your answer to four significant figures and include the appropriate units.

Your answer is 32 hope i  

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
