Asmall projectile is fired vertically downward into a fluid medium with an initial velocity of 60 m> s. due to the drag resistance of the fluid the projectile experiences a deceleration of a = (-0.4v3) m> s2, where v is in m> s. determine the projectile’s velocity and position 4 s after it is fired!

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?
