Two material points move along the x-axis according to the equations x1 = A1 B1 C1t2 and x2 = A2 B2 C2t2, where A1 = 10 m, B1 = 2 m / s, C1 = -2 m / s2, A2 = 3 m, B2 = 1 m / s, C2 = 0.2 m / s2. Determine the speeds V1 and V2 and the accelerations of these points at the time when their speeds are the same; at the moment in time when the points occupy the same position on the x-axis.
