In a head on collision between two cars traveling at 20 m/s (44.7 mph), both cars are brought to a complete stop in 150 ms. Part A: calculate the restraining force required on a 87.2 kg passenger to remain firmly in their seat during such a head on impact. Part B: The weight of an average 175 pound adult is 778 newtons. Imagine if a person in the backseat of one of these cars chose not to wear their seatbelt and instead attempted to use their arms to hold them selves against the seat back. To visualize the strength required to accomplish this, calculate the number of average adults this person have to be able to hold up against gravity in order to accomplish this feat. The restraining forces in part a is equivalent to the combined weight of how many 175 pound adults?

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
