A124-kg balloon carrying a 22-kg basket is descending with a constant downward velocity of 27.3 m/s a 1.0-kg stone is thrown from the basket with an initial velocity of 16.8 m/s perpendicular to the path of the descending balloon, as measured relative to a person at rest in the basket. the person in the basket sees the stone hit the ground 7.60 s after being thrown. assume that the balloon continues its downward descent with the same constant speed of 27.3 m/s . a- how high was the balloon when the rock was thrown out? b- how high is the balloon when the rock hits the ground? c- at the instant the rock hits the ground, how far is it from the basket? d- just before the rock hits the ground, find its horizontal and vertical velocity components as measured by an observer at rest in the basket. e- just before the rock hits the ground, find its horizontal and vertical velocity components as measured by an observer at rest on the ground.

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
