5. A student places a rectangular rubber eraser on a leather-bound book, and begins to tilt the book. If the coefficient of friction between leather and rubber is 0.61, at
what angle will the eraser first start to slide?
O A. 24°
8.32
OC.38
D. 52

As we gain mass the force of gravity on us increases!

What does the start look like

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18
