find the frictional force between an air hockey puck and the table, assume u air = 1.8 X 10^-5 kg/ms, the puck is 0.013 above the table, the puck has an area of 25 cm^2
To find the frictional force between the air hockey puck and the table, we can use the equation:
Frictional Force = Coefficient of Friction * Normal Force
First, let's find the normal force acting on the puck. The normal force is equal to the weight of the puck, which can be calculated as:
Weight = Mass * Gravity
The mass of the puck is not provided, so we would need that information to proceed further. However, assuming you know the mass of the puck, let's continue with the calculation.
Next, we need to calculate the area of the puck in square meters. The given area is in square centimeters, so we need to convert it. There are 100 square centimeters in a square meter, so:
Area (in square meters) = Area (in square centimeters) / 10000
Now that we have the area, the coefficient of friction (u air), and the normal force, we can calculate the frictional force:
Frictional Force = u air * Area * Normal Force
Substitute the values into the equation and solve for the frictional force.
