SOLVED - Just a quick check for my solutions - ice patch friction
Say you (65kg) take a brisk ice skate across a frictionless lake when suddenly you hit a rough patch of ice that's 10 m long with a coefficient of friction (0.02). If you were traveling at 75 m/s before you hit the patch, how fast would you be traveling ater the patch? How long would the patch have to be in order for you to stop?
Work equations
I got 74.97 m/s after the 10m ice-patch, that the ice-patch would need to be 14335.09762m long for you to stop completely, and as a bonus, I calculated the acceleration that you would experience to be -0.1962 m/s²
I just wanted to check if my answers are correct for this - thank you in advance :)
