While sitting on a frozen pond, a 35kg child throws a 0.5kg ball horizontally at a velocity of +6m/s. Calculate the resulting velocity of the child across the ice.Suppose the child throws the ball upward instead, at a 25o angle above horizontal. a) Calculate the resulting velocity of the child across the ice. b) Calculate the vertical impulse delivered to the child (and therefore, to the ice).
