Question

A .250kg object hands from a spring and oscillates with an amplitude of 5.42 cm (.0542m). If the spring constant is 48.0 N/m, determine the acceleration of the object when the displacement is 4.27cm (.0427m) [down]. What is the maximum speed?

Answer 1

The net force which produces acceleration in mass is F=-Ky
or, ma=-Ky
or, a=-(K/m)y
where, y is displacement from mean position
K is spring constant
m is mass
