Question

A 2.70 kg book rests on an incline of 13.0. You give it a sharp push up the frictionless ramp. It comes to a stop in 25.25 at 17.5 m up the ramp before starting its descent(a) What is the magnitude of the normal force on the book

Answer 1

the magnitude of the normal force on the book is 25.78N

Step-by-step explanation:

The computation of the magnitude of the normal force on the book is shown below

Normal force = N is

= mgcosβ

= 2.70 × 9.8 × cos13°

= 25.78N

hence, the magnitude of the normal force on the book is 25.78N

The above formula should be applied
