Hockey Puck Momentum Conservation of Momentum
Hockey Puck Velocity
Clown Cannon
Consider the same system as before: A hockey puck with a mass of 0.17 kg is traveling to the right along the
ice at 15 m/s. It strikes a second hockey puck with a mass 0.11 kg. The first hockey puck comes to rest after the
collision. If conservation of momentum holds, what is the total final momentum of the system? (Round your
answer to the nearest tenth.)

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
