Alex pushes on a 2.0 kg book, resulting in a net force of 6.0 N on the book. What is the acceleration of the book?

A 3.0m/s

B 12m/s

C 24m/s

D 1.5m/s

Verified Answer :

the answer is D. 3.0 m/s
force is mass × acceleration due to gravity
force = 6.0 N
mass = 2.0 kg
acceleration = ?
f = m×a 
6 = 2×a
a = 6÷3
a = 3.0 m/s

Answer:

The acceleration of the book \(a=3\ m/s^2\)

Explanation:

It is given that,

Mass of the book, m = 2 kg

Force acting on the book, F = 6 N

We need to find the acceleration of the book. It can be calculated using second law of motion. Force is the product of the mass of an object and its acceleration.

F = ma

\(a=\dfrac{F}{m}\)

\(a=\dfrac{6\ N}{2\ kg}\)

\(a=3\ m/s^2\)

So, the acceleration of the book is \(a=3\ m/s^2\). Hence, this is the required solution.
