A particle of mass m= 1.18kg is attached between two identical springs on a frictionless, horizontal tabletop. Both springs have spring constant k and are initially unstressed, and the particle is at x=0(d) If the particle is pulled 0.500m to the right and then released, what is its speed when it reaches x=0?

L Corporation produces and sells 15,200 units of Product X each month. The selling price of Product X is $22 per unit, and variable expenses are $16 per unit. A study has been made concerning whether Product X should be discontinued. The study shows that $73,000 of the $102,000 in monthly fixed expenses charged to Product X would not be avoidable even if the product was discontinued. If Product X is discontinued, the annual financial advantage (disadvantage) for the company of eliminating this product should be: Multiple Choice ($39,800) $39,800 ($62,200)
