Two ponies of equal mass are initially at diametrically opposite points on the rim of a large horizontal turntable that is turning freely on a vertical, frictionless axle through its center. the ponies simultaneously start walking toward each other across the turntable. as they walk, what happens to the angular speed of the turntable? (a) it increases(b) it decreases(c) it stays constantconsider the ponies-turntable system in this process is the angular momentum of the system conserved? (a) yes(b) no
