An object of mass 100 kg is initially at rest on a horizontal frictionless surface. at timet-0, a horizontal force of 10 n is applied to the object for 1 s and then removed. which of the following is true of the object at time t = 2 s if it is still on the surface? (a) it is at the same position it had at t 0, since a force of 10 n is not large enough to move such a massive object. (b) it is moving with constant nonzero acceleration. (c) it is moving with decreasing acceleration. (d) it is moving at a constant speed (e) it has come to rest some distance away from the position it had att 0.

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:
