###### 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

## Answers

Answer: the magnitude of the normal force on the book is 25.78NExplanation:The computation of the magnitude of the normal force on the book is shown belowNormal force = N is = mgcosβ= 2.70 × 9.8 × cos13°= 25.78N hence, the magnitude of the normal force on the book is 25.78NThe above formula should be applied
