The acceleration of the book is the local acceleration of gravity near the surface of the Earth, g = 9.8 m / s² down.
The weight of the book is equal to mass * g.
In this case, ( 2.26 kg ) ( 9.8 m / s² ).

a. acceleration is gravity acceleration which 9.8 m/s²
b.Force = ma
Force is the weight
acceleration is the gravity acceleration
m is mass of object
weight = mg
weight=2.26 x 9.8
weight=22.148 N

a)..Acceleration due to Gravity = 9.81m/s². (The full figure).
b)..Weight (Force) = Mass(kg) x Acceleration (F = ma)
= 2.26kg x 9.81m/s² = 22.17 Newtons.
