Question

Roberto and Laura are studying across from each other at a wide table. Laura slides a 2.2 kg book
toward Roberto. If the net force acting on the book is 1.6 N to the right, what is the book's acceleration?

Answer 1

Explanation:

Force = Mass × Acceleration

1.6 = 2.2 × a

a = 1.6/2.2

= 0.73 m/s^2

Note that the acceleration will be negative.

Answer 2

Answer: The acceleration of the book is $0.73m/s^2$  

Explanation:

Force is defined as the push or pull on an object with some mass that causes change in its velocity.

It is also defined as the mass multiplied by the acceleration of the object.

Mathematically,

$F=ma$

where,

F = force exerted on the book = 1.6 N

m = mass of the book = 2.2 kg

a = acceleration of the book = ?

Putting values in above equation, we get:

$1.6kg.m/s^2=2.2\times a\\\\a=\frac{1.6}{2.2}=0.73m/s^2$

Hence, the acceleration of the book is $0.73m/s^2$
