You are an industrial engineer with a shipping
company. As part of the package-handling system, a small box
is placed against a light spring that is compressed
0.280 m. The spring has force constant
46.0 N/m .
The spring and box are released from rest, and the box travels
along a horizontal surface for which the coefficient of kinetic
friction with the box is
k = 0.300. When the box has traveled
and the spring has reached its equilibrium length, the box
loses contact with the spring.
What is the speed of the box at
the instant when it leaves the spring?
What is the maximum
speed of the box during its motion?
