Question

6. What is the mass of an object that requires a force of 30 N to accelerate at 5 m/s??

Answer 1

According to the Newton's second law,

`F=ma`

where F is the force on the object, m is the mass of the obect and a is the acceleration of the object.

Substituting the known values,

`30=m*5`

Thus, the mass of the object is,

`\begin{gathered} m=(30)/(5) \\ m=6\text{ kg} \end{gathered}`

Hence, the mass of the object is 6 kg.
