7. A spring with negligible mass and force constant k is kept straight by confining it within a smooth-walled vertical tube (no friction). The spring is initially compressed by an amount y, and held there by a latch pin inserted through the wall of the tube. A smooth ball of mass m is placed in contact with the spring as shown in the figure. The latch pin is removed. 7a) What will be the speed of the ball (in terms of k, m, and y,) as it leaves contact with the spring? (Hint: Your answer can also have g for the acceleration of gravity.) (Hint: Carefully define your coordinate system and where you would like to place y = 0.)

Transcribed Image Text:7. A spring with negligible mass and force constant k is kept
straight by confining it within a smooth-walled vertical
tube (no friction). The spring is initially compressed by
an amount y, and held there by a latch pin inserted
through the wall of the tube. A smooth ball of mass m is
placed in contact with the spring as shown in the figure.
The latch pin is removed.
