Question

Calculate the frictional coefficient of a kayak with a weight of 180.0 N being pulled through the water with a force of 65.0 N and a fluid frictional force of 30.0 N.

A) 0.067
B) 0.156
C) 0.334
D) 0.423

Answer 1

The coefficient of friction can be calculated using the formula µ = Ffriction / Fnormal. In this case, the coefficient of friction of the kayak can be found to be 0.857.

Step-by-step explanation:

The coefficient of friction can be calculated using the formula μ = Ffriction / Fnormal;

Where Ffriction is the frictional force and Fnormal is the normal force.

In this case, we are given the force being exerted on the kayak and the fluid frictional force. The normal force can be calculated by subtracting the fluid frictional force from the force being exerted on the kayak:

Fnormal = F - Ffluid friction

Substituting the given values, we have Fnormal = 65.0 N - 30.0 N = 35.0 N

Now, we can calculate the frictional coefficient using the formula:

μ = Ffriction / Fnormal = 30.0 N / 35.0 N = 0.857
