Since we already know that T = T
of the forces of the block on the table in both the x and y axis directions.
So, our key for solving this puzzle is that the normal force N is equal to the object's
weight, and the force of static friction f
already know the masses of both objects, and we also know that f
and N is the weight of W. So, all that's left is to calculate the forces. To solve for this in
terms of force, first convert the weights to SI units of kg. Then, convert the masses to
newton forces, and finally, plug these values into the equation for the coefficient of
kinetic friction.
First, convert to SI units of kg:
