Question

An object weighing 88 N is pushed by a 100 N force. What is the acceleration of the object?

Answer 1

Given data:

* The weight of the object is 88 N.

* The force acting on the object is 100 N.

Solution:

The weight of the object in terms of the mass of the object is,

`W=mg`

where m is the mass of the object, and g is the acceleration due to gravity,

Substituting the known values,

`\begin{gathered} 88=m*9.8 \\ m=(88)/(9.8) \\ m=8.98\text{ kg} \end{gathered}`

According to Newton's second law, the acceleration of the object in terms of the force acting on the object is,

`F=ma`

where a is the acceleration of the object,

Substituting the known values,

`\begin{gathered} 100=8.98* a \\ a=(100)/(8.98) \\ a=11.14ms^(-2) \end{gathered}`

Thus, the acceleration of the object is 11.14 meters per second squared.
