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