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

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

Answer 2

Answer: 6 kg

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

$F=m\times a$

Given: F= Force = 30N=$30kgms^{-2}$

m= mass = ?

a = acceleration= $5ms^{-2}$

Putting the given values in the formula:

$30kgms^{-2}=m\times 5ms^{-2}$

$m=6 kg$

Thus mass of the box= 6kg
