The steel ball a of diameter d = 25 mm slides freely on the horizontal rod of length l = 169 mm which leads to the pole face of the electromagnet. the force of attraction obeys an inverse-square law, and the resulting acceleration of the ball is a = k/(l - x)2, where k = 100 m3/s2 is a measure of the strength of the magnetic field. if the ball is released from rest at x = 0, determine the velocity v with which it strikes the pole face.
