In this scenario, you will play the role of a Traffic Accident Investigator. On this
particular day, you encounter an accident
where a driver in a truck entering an
intersection is hit from the side by car going
through the intersection. The driver in the
car claimed that the driver of the truck was
at fault, "I had the right of way, I was going
the speed limit and the truck pulled right
out in front of me!" The driver in the truck
claimed, "I would have made it safely,
except the car was going way over the
speed limit. I couldn't know the car was
going so fast, its the car's fault for
speeding."

Avalue that describes how heavy an object is and is related to the force of gravity is

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
