Question: A block of mass m is attached to a spring of constant k. The block isreleased from rest when the spring is in a horizontal and undeformed position.Use computational software to determine, for various selected values of k/mand r0,
(a) the length of the spring and the magnitude and direction of thevelocity of the block as the block passes directly under the point of suspensionof the spring,
(b) the value of k/m when r0 5 1 m for which that velocity is horizontal.5 ftv0qF
