A block of mass m sliding on a frictionless table isattached to a string that passes through a narrow hole through thecenter of the table. The block is sliding with speedv0 in a circle of radiusr0. (Use the following variables as necessary:r_0 for r0, m, and v_0 forv0)

(a) Find the angular momentum of the block.

(b) Find the kinetic energy of the block.

(d) A student under the table now slowly pulls the string downward.How much work is required to reduce the radius of the circle fromr0 to r0/2?
