A person pushes two boxes with a horizontal 100 N force on a frictionless floor, as shown in the figure. Box A is heavier than box B. Which statement about these boxes is correct? The boxes move with constant velocity. A. Box A pushes on box B harder than box B pushes on box A.
B. Box A pushes on box B with a force of 100 N, and box B pushes on box A with a force of 100 N.
C. Boxes A and B push on each other with equal forces of less than 100 N.
D. The boxes will not begin to move unless the total weight of the two boxes is less than 100 N.

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:

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
