Question
A 110g hockey puck sent sliding over ice is stopped by a frictional force on it from the ice a) if its intial speed is 6.0m/s, what is the magnitude of the frictional force? b) what is the coefficient of friction between the puck and the ice?
I am unsure how to solve the first part of the problem because they give met only intial velocity and distance but no time. I assuming that 15 m stands for meters. Please give me some direction thank you
If you know the distance, you can use:
Vf^2 = vo^2 + 2ad,
Vf is final velocity; vo is initial velocity, and d is distance. Once you know a, you can calculate the force.
