Question

A 1.50 kg book is set on a slanted coffee table. The coffee table is slanted at an angle of 25 degrees with respect to the horizontal.
a.) What is the normal force acting on the book?

b.) What is the minimum coefficient of static that would keep the book on the table? A 1.50 kg book is set on a slanted coffee table. The coffee table is slanted at an angle of 25 degrees with respect to the horizontal.

a.) What is the normal force acting on the book?

b.) What is the minimum coefficient of static that would keep the book on the table?

Explanation / Answer

a) Normal force on the book = mg * cos(theta) (as the book is not accelerating in vertical direction)

Normal force on the book = 1.50 * 9.8 * cos(25)

Normal force on the book = 13.3 N

b)

minimum coefficient of static friction = tan(theta)

minimum coefficient of static friction = tan(25 degree)

minimum coefficient of static friction = 0.466
