... A car turns off a residential street with a speed limit of 60km/h (17m/s) to a highway with a speed limit of 110km/h (31m/s). While in the merge lane, it takes the driver 12s to accelerate to the highway speed. Draw a graph, and use it to find the acceleration of the driver. Find the area under the ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
