If person A is 150N and is being pulled by a force of 200N along the skating rink floor at a acceleration 10m/s^2. What is the coefficient of friction between the skates of person A and the floor? See the diagram below.
Sum of the forces:
On one rainy cold Friday afternoon Parish students, Toi, Amshi, Moriah and I, decided to have a great afternoon filled with friction and fun! They all went to an inline skating rink in Dallas, Texas. There they saw their favorite physics teacher Ms.Gende. The smart students and their teacher all sat down when suddenly Amshi begins to share her thoughts on the physics of rollerblading. She said that the there is a force of friction between the skates and the floor and the forward force of the person skating forward. After thirty minutes of discussing physics the announcer calls everyone to the skating rink who wanted to play a game. With everyone in pairs and in skates person A stands upright holding a rope while person B stands in front of person A holding the rope too. Toi asks Taylor “ I wonder what the friction is between my skates and the floor?” . " Well let’s see if we can use what we learned in physics to come up with an equation!!!” says Taylor.
