1. The problem statement, all variables and given/known data A ball on a porch rolls 60 cm to the porch's edge, drops 40 cm, continues rolling on the grass, and eventually stops 80 cm from the porch's edge. What is the magnitude of the ball's net displacement, in centimeters? 2. Relevant equations d = a^2 + b^2 3. The attempt at a solution So there seems to be two triangles, each having 2 known sides. So I found the displacement of sides 60 and 40 and got 72.111 cm Then for the 2nd triangle I found the displacement of sides 40 and 80 and got 89.443 cm. The next step I was confused on. But I went ahead and put the two vectors together and I used the p.theorem to take the square root of 89.443^2 and 72.111^2 and came up with 114 cm as the net displacement. Is this right or way off. My dumb book doesn't give the answer.
