Leaving from a height of 0.3 m on an inclined plane, a body with a mass of 0.2 kg travels along a horizontal plane and compresses a spring arranged as shown in the figure. Disregarding friction: describe the energy transformations involved in this movement; calculate the energy gained by the spring; determine the deformation of the spring knowing that its elastic constant k = 5 N/m; justify the statement that, being a conservative system, the block will go up and down the ramp indefinitely.

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:
