A child in a boat throws a 5.70-kg package out horizontally with a speed of 10.0 m/s. The mass of the child is 18.2 kg and the mass of the boat is 38.6 kg (Figure 1) Figure < 1 of 1 4 Part A Review Constants Calculate the velocity of the boat immediately after, assuming it was initially at rest. Express your answer to three significant figures and include the appropriate units. Enter positive value if the direction of the velocity is in the direction of the velocity of the box and negative value if the direction of the velocity is in the direction opposite to the velocity of the box. HA ? v = 10.0 m/s v' Value m/s
