A force of 15.00 N to the right causes a 2.02 kg book to have a net acceleration of 0.81 m/s2 to the right. What is the frictional force acting on the book?
F - Ff = M a
Ff is the friction force
Ff = F - Ma = 15.00 - 1.64 N = 13.36 N
Awesome, thanks!
To find the frictional force acting on the book, we need to use Newton's second law of motion. The formula for Newton's second law is:
F = m * a
where F is the net force acting on the object, m is the mass of the object, and a is the acceleration of the object.
In this case, we know that the net force acting on the book is 15.00 N to the right and the acceleration of the book is 0.81 m/s² to the right. The mass of the book is given as 2.02 kg.
So, let's substitute the values into the formula:
15.00 N = 2.02 kg * 0.81 m/s²
Now, solve for the frictional force:
Frictional force = 15.00 N - (2.02 kg * 0.81 m/s²)
Frictional force = 15.00 N - 1.6434 N
Frictional force = 13.36 N
Therefore, the frictional force acting on the book is 13.36 N.
