The mass of the gear is 48 kg and it has a radius of gyration of ko = 125 mm. The mass of the gear rack is 22 kg. Assume that the contact surface between the gear rack and the horizontal plane is smooth. (Figure 1) Figure 150 mm- 75 mm vira 1 of 1 P = 150 N Part A If the cord is subjected to a horizontal force of P = 150 N, and gear is supported by a fixed pin at O, determine the angular velocity of the gear in 1 s, starting from rest. Express your answer to three significant figures and include the appropriate units. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise.
