A small child’s leg when she walks can be modeled as uniform circular motion. Assume that each hip moves in a circular arc equal to the length of the leg, with the weight-bearing foot at the center of the circle and the child’s entire mass concentrated near the hip. Calculate the maximum speed vmax at which she can walk if her weight is 20 kg and the length of her leg is 30 cm. A. 1.52 m/s
B. 1.71 m/s
C. 2.94 m/s
D. 3.00 m/s

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
