Final answer:
The force of friction acting on you as you slide across a tile floor with a coefficient of friction of .25 and a normal force of 650 N is 162.5 N.
Step-by-step explanation:
The coefficient of friction is a dimensionless quantity that represents the ratio of the force of friction between two bodies and the force pressing them together. When calculating the force of friction acting on you as you slide across a floor with a given coefficient of friction, you can use the following formula: f = μN, where f is the force of friction, μ is the coefficient of friction, and N is the normal force. In this scenario, with a normal force of 650 N and a coefficient of friction of 0.25, the force of friction is calculated as f = (0.25)(650 N) = 162.5 N.
