model rocket a is launched at an angle of 70° above the x axis, with an initial velocity of 40 m/s. an identical rocket b is launched under the same conditions at an angle of 90° above the x axis, also with an initial velocity of 40 m/s. which is the true statement about the horizontal distances the rockets will cover?
a. rocket a will travel farther horizontally than rocket b.
b. rocket b will travel farther horizontally than rocket a.
c. the rockets will travel the same horizontal distances but will do so in different amounts of time.
d. there is not enough information to answer this question.

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:

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
