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? ball starts rolling here \/ rolls 60cm-> #----------# ******** - ******** - <- ball goes down 40 cm ******** - ******** #-----------------# <---ball stops rolling here ..................ball rolls 80cm ^ 2. Relevant equations The length of both a and b are known for both triangles, then c, the hypotenuse, can ...................................... _________ be calculated as follows: c=√a^2+b^2. 3. The attempt at a solution 72 cm and 89 cm are the hypotenuse's of two different triangles. The first triangle is 40 and 60; The hypotenuse is 72 cm. The second is 40 and 80: this one's hypotenuse is 89 cm. I need to find the magnitude of the ball's net displacement. This is where I'm confused. And have I done this problem correct up to this point or am I way off?
