... Example 4: What is the maximum acceleration for the 2-kg mass in the previous problem? (A = 12 cm, k = 400 N/m) The maximum acceleration occurs when the restoring force is a maximum; i.e., when the stretch or compression of the spring is largest. ...

... 22. A 7.0 kg bowling ball strikes a 2.0 kg pin. The pin flies forward with a velocity of 6.0 m/s, the ball continues forward at 4 m/s. What was the original velocity of the ball? 23. Wiley Coyote has missed the elusive roadrunner once again. This time, he leaves the edge of the cliff at 50.0 m/s hor ...

Coefficient of Sliding Friction
... • Place the block on its narrow side with, perhaps, 500 grams stacked on it. Readjust the pulley so that the cord is again parallel to the plane. Find the value of m necessary to cause the block to slide at constant speed. This will be your test to see if the frictional force has any dependence on t ...

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.
