A toboggan having a mass of 14.5 kg starts from rest at A and carries a girl and boy having a mass of 40 kg and 45 kg, respectively. When the toboggan reaches the bottom of the slope at B, the boy is pushed off from the back with a horizontal velocity of vb/t = 2 m/s, measured relative to the toboggan. Suppose that h = 2.5 m. Neglect friction in the calculation. B Determine the velocity of the toboggan afterwards. Express your answer to three significant figures and include the appropriate units. ? V = Value Units
