Physics Unit 2 Discussion Based Assessment. Show your work for full credit: Draw a graph that shows the displacement of an object over a given time moving at a constant speed.

Blue drops his tennis ball from a balcony. It strikes Mr. Dilley’s head 0.30 s later. How high is the balcony at the point Blue dropped his ball?

Mr. Dilley drops a rock from a 40 m high bridge. Ignoring air resistance, how long will it take for the rock to strike the surface of the river below?

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:
