Chapter 8, Problem 21P
(II) When a mass m sits at rest on a spring, the spring is compressed by a distance d from its undeformed length (Fig. 8–33a). Suppose instead that the mass is released from rest when it barely touches the undeformed spring (Fig. 8–33b). Find the distance D that the spring is compressed before it is able to stop the mass. Does D = d? If not, why not?

A mass m is attached to a spring which is held stretched a
distance x by a force F, Fig. 6–45, and then released.
The spring pulls the mass to the left, towards its natural
equilibrium length. Assuming there is no friction, determine
the speed of the mass m when the spring returns: (a) to its
normal length (x = 0); (b) to half its original extension
(x/2).

FIGURE 6–45 Problem 75.
A compressed spring fires a ball of mass (m) directly upwards.
If the mass of the ball and the initial compression of the spring are both tripled (3x), (neglect air resistance) then,
(a) The ball will reach thrice (3x) the height as before.
(b) ball will reach four times (4x) the height as before.
(c) The ball will reach half (0.5x) of the height previously reached.
(d) The ball will reach the same (1x) height as before.
(e) The ball will reach one quarter (0.25x) of the height previously reached.
(f) The ball will reach twice (2x) the height as before.
which answer is correct?
14–83. A rocket of mass m is fired vertically from the surface
of the earth, i.e., atr = r. Assuming that no mass is lost as it
travels upward, determine the work it must do against gravity
to reach a distance n. The force of gravity is F = GM,m/²
(Eq. 13–1), where M is the mass of the earth and r the distance
between the rocket and the center of the earth.
