50 N Boxes A and B are in contact on a horizontal, frictionless surface, as shown in the figure above. Box A has mass 2.50 kg and box B has mass 7.50 kg. A horizontal force of 50.0 N is exerted on box B. If the boxes are initially at rest, what is the average power produced by the normal force that box A exerts on box B when the boxes move a distance of 10.0 m?

Transmission Delay
Consider sending N packets each of length L bits from Host A to
Host B, as shown in the figure below. Assume that the links between
Host A and the Router and between the Router and Host B each has a
transmission rate of R bits per second. Assume all buffers are of
infinite capacity. Ignore all processing and propagation
delays.
a) Express the delay it takes to send 2 packets
from A to B as a function...

Shown in the figure is a gear driven squeeze roll which mates with an idler roll (not shown). The roll is designed to exert a normal force of 30 lb/in of roll length and a pull of 24 lb/in on the material being processed. The roll speed is 300 rev/min and an L10 life of 30 kh is desired. Use an application factor for poor bearing seals and commercial gearing. Select a pair of radial contact 6300-series medium, deep groove...
