In early test flights for a space shuttle using a "glider" (mass of 1000kg including pilot), it was noted that after a horizontal launch at 500 km/h at a height of 3500m, the glider eventually landed at a speed of 200 km/h. a) What would its landing speed have been in the absence of air resistance?b) What was the average force of air resistance exerted on it if it came in at a constant glide of 10 degrees to the Earth?

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j.suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon

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:
