Homework Statement
1. Dubbie is moving directly along a normal line toward a plain mirror at a speed of 3.5 m/s, what is the speed of the image relative to Dubbie?
2. What is the speed of the image, relative to Dubbie, if Dubbie walk away from the mirror surface at 3.5 m/s at an angle of 300 to the mirror surface
Homework Equations
Do = Di
The Attempt at a Solution
I think that both of the answers are 3.5 m/s. Except I am pretty sure that the 30 degree in the 2nd question will change something somehow, but I'm not sure which equation to use...
