- The platform is rotating about the vertical axis such that at any instant its angular position is 0 = 4t3/2 rad, where t is in seconds. A ball rolls outward along the radial groove so that its position is r = 0.1t³ m, where t is in seconds. Determine the magnitude of velocity of the ball (m/s) when t = 2.60 seconds.Chapter 37, Problem 012 The length of a spaceship is measured to be exactly 1/2 its rest length.
