a)A child with mass of Y kilograms (kg) who is sliding eastward in a hockey rink at Y centimeters per second (cm/s) runs into another child, also with mass of Y kg, who is skating northward at Z cm/s. The children grab onto each other and keep moving across the ice. Draw a diagram of this interaction, labeling all the relevant objects, quantities, and velocity vectors before and after the collision.

b) What is the velocity (magnitude and direction) of the two children after they collide? Your answer should be significant to two digits. Show all your calculations and use correct units.

c) Do you think these two children are likely to have been injured in the collision? In a paragraph explain using scientific and mathematical reasoning why you think so or not.

Y=4

Z=39
