9. A mass weighing 8 pounds stretches a spring 3 feet. A damping force numerically equal to 3 times the instantaneous velocity acts on the system. Determine the equation of motion x(t) if the mass is initially released from the equilibrium position with an upward velocity of 2 ft/s. The problem is modeled by the differential equation with initial values:

For a rotating object rotating in a circle with constant angular speed, the ONLY force acting on the object is a centripetal force keeping it in a circular orbit.

A uniform 39.0-N board supports two children weighing 510 N and 350 N. If the support is at the center of the board and the 510-N child is 1.4 m from its center to the left of the support, how far is the 350-N child from the center if the system is balanced? Two significant digits.
