Game design why are simple shapes used to detect collision in many games, including the car example in unity? in what kind of games might it be “worth” integrating more complicated geometry for collision detection?

Because, to put it simply, to use more complicated shapes requires more processing power which is unnecessary. Only if they would touch all parts of the shape should it be complicated.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
