Question

The weight of body is 420N. calculate its mass.​

Answer 1

Step-by-step explanation: weight = 420N

mass= ?

we know,

weight = mass . acceleration due to gravity

or, 420 = mass . 9.8

therefore mass = 42.85 kg

Answer 2

mass = 42 kg

Explanation:

We know that we have the formula that

W = m * g

Then

given

weight (w) = 420

g = 10 m/s²

then

W = m* g

420 = m * 10

m = 420/10

m = 42 kg

Hope it helps :)
