Question

A force of 240 N causes an object to accelerate at 3.2 m/s2. What is the mass of the object?

A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?

Answer 1

B.75 kg

Step-by-step explanation:

Given parameters:

Force on the object = 240N

Acceleration of the object = 3.2m/s²

Unknown:

Mass of the object = ?

Solution:

Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;

Force = mass x acceleration

The unknown here is the mass, simply input the parameters and solve for it;

240 = mass x 3.2

mass =
`(240)/(3.2)` = 75kg

The mass of the object is 75kg
