Question

Amanda pushes a box across the room with a force of 30 N. It accelerates at 5 m/s/s. What is the mass of the box? *

6 kg
1.16 kg
30 kg
5kg

Answer 1

Answer: 6 kg

Explanation: Force is defined as a push or pull which results when an object interacts with another object.

`F=m* a`

Given: F= Force = 30N=
`30kgms^(-2)`

m= mass = ?

a = acceleration=
`5ms^(-2)`

Putting the given values in the formula:

`30kgms^(-2)=m* 5ms^(-2)`

`m=6 kg`

Thus mass of the box= 6kg

Answer 2

Given:

Force (F) acting on the box = 30 N

Acceleration produced (a) = 5 m/s2

To determine:

The mass (m) of the box

Calculation:

Formula: F = ma

m = F/a = 30/ 5 = 6 kg

Ans: Mass of the box is 6 kg
