Construct a full model (i. e., figure out everything you can) for the motion described below.

A monorail starts from rest and accelerates at a rate of 2.2 m/s2 for 10 s. Then it
runs at a constant speed for 74 s and then slows down at a rate of 1.5 m/s2.

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:
