On earth, froghoppers can jump upward with a takeoff speed of 2.8 m/s. suppose you took some of the insects to an asteroid. if it is small enough they can jump free of it and escape into space. (a) what is the diameter (in km) of the largest spherical asteroid from which they could jump free? assume typical asteroid denisty of 2.0 g/cm^3. (b) suppose that one of the froghoppers jumped horizontally from a small hill on an asteroid. what would the diameter (in km) of the ateroid need to be so that the insect could go into a circular orbit just above the surace?

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:

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
