Then solve the problem by filling in the squares and triangles with the correct meters. Then add all the meters together on both sides. One side should be positive the other negative. Does the final meters add up to 0? If not the man did not return to his starting location.

- A PHYS 1510 student decides to take revenge on the awful Canadian Goose that has been chasing it all over the campus. The student ambushed the goose, jumping off a short wall to startle it. The student weighs 49.2kg. The wall is 1.47m tall. Initial speed was 1.767 m/s because the student pushed off when jumping. What was the student's speed when they reached the ground?
