Two balloons (m = 0.021 kg) are separated by a distance of d = 16 m. they are released from rest and observed to have an instantaneous acceleration of a = 1.1 m/s2 toward each other at the moment they are released. assume the two balloons are point charges and have equal but opposite charges
(a) calculate the magnitude of the charge on each balloon in c.
(b) how many electrons are responsible for the charge, 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:
