The acceleration of a point P, moving along a straight line, is directed to the point Z and its magnitude is inverse proportional to the distance x. For t=0 the point P has the distance Xo = 2 m, the velocity vo = 4 m/s and the acceleration a = -3 m/s. a) Determine the velocity v for the distance x = 3 m. b) At what distance x the velocity is zero? Z X P
