Know the answer to this question? Two cars equal mass (1,000 kg each) involved in a rear wnd accident at a stop sign. Here is what you know.

. Car 1 approached intersection from the top at 25 meter hill.

. Car 2 was on a flat stretch of road directly in front of Car 1

. At the bottom of the hill, Car 1 was going 20 m/s, Car 2 at 30 m/s before it stopped at the stop sign.

. There was no skid marks left by Car 2. The collision occurred at the stop sign, where car 2 had stopped.

. After the collision, both cars were moving together in the same direction at 10 m/s before slowly rolling to a stop.

. You must now push Car 2, using 800N of force, 10 meters off to the side of the road so no one gets hurt.

7) Assuming that there are no other nonconservatice forces involved, what inpluse was given to each car during the collision?

A. Car 1 -

B. Car 2 -

8. How many energy did Car 1 lose in the collision?

9. How much energy did Car 2 gain in the collision?

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

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
