Question 6 A disc rolls on a horizontal surface without slipping as shown below. The centre P of the disk has a velocity of 3.4 m/s to the right, and the radius of the disc is 195 mm, with point B located halfway along the radius as shown. Determine the y-component of the velocity of B for this instant. Express your answer to three significant figures, in units of mm/s (but do not include the units in your answer).
