Suppose the spring in Fig. 3-2 is stretched twice as it x=2A). What happens to (a) the energy of the system,
the maximum velocity of the oscillating mass, (c) the
Toy dart gun. A dart of mass 0.100 kg is pressed against
the spring of a toy dart gun as shown in Fig. 3–3a. The
spring, with spring stiffness constant k=250 N/m and
ignorable mass, is compressed 6.0 cfm and released. If the
dart detaches from the spring when the spring reaches its
Example 3.4:
maximum acceleration of the mass?

natural length (x=0), what speed does the dart acquire?

Natural forces that can alter ecosystems include seasons and climate changes. t or f
