Unformatted text preview: d) Not enough information is given. 4) Two identical twins ride on a merry-go-round, with twin A at a greater distance from the axis of rotation than twin B. Which is the most accurate statement? a) The kinetic energy of twin A is greater than the kinetic energy of twin B. b) The kinetic energy of twin A is less than the kinetic energy of twin B. c) The kinetic energy of twin A is equal to the kinetic energy of twin B. d) Not enough information is given. 5) Yo-yo man releases a yo-yo from rest and allows it to drop, as he keeps the top end of the string stationary. The mass of the yo-yo is 0.056 kg, its moment of inertia is 2.9 x 10-5 kg m 2 , and the radius, r, of the axle the string wraps around is 0.0064 m. Neglect the mass of the string. What is the linear speed of the yo-yo after it has dropped through a height of 0.50m? www.clas.ucsb.edu/staff/vince r...
