Military rifles have a mechanism for reducing the recoil forces of the gun on the person firing it. an internal part recoils over a relatively large distance and is stopped by damping mechanisms in the gun. the larger distance reduces the average force needed to stop the internal part. (assume the gun is fired in the positive direction.)
(a) calculate the recoil velocity (in m/s) of a 1.07 kg plunger that directly interacts with a 0.0200 kg bullet fired at 571 m/s from the gun. (indicate the direction with the sign of your answer.) 10.67 m/s (b) if this part is stopped over a distance of 18.2 cm, what average force (in n) is exerted upon it by the gun? (indicate the direction with the sign of your answer.) -334.66x n .
(c) compare this to the force exerted on the gun if the bullet is accelerated to its velocity in 12.4 ms.

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
