A5.0-kg object is suspended from the ceiling by a strong spring, which stretches 0.20 m when the object is attached. the object is lifted 0.060 m from this equilibrium position and released. part a determine the amplitude of the resulting simple harmonic motion.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
