You swing a hammer down onto a wedge. Which of the following choices best describes the input and output forces? A. The wedge exerts a greater output force than the input force supplied, and it applies the force over a greater distance.
B. The wedge exerts a greater output force than the input force supplied, but as a consequence the greater force is applied over a smaller distance.
C. The wedge exerts a smaller output force than the input force supplied, but it applies the force over a greater distance.
D. The wedge exerts a smaller output force than the input force supplied, but it increases the amount of work done.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
