Answer:

mass = 42 kg

Step-by-step 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 :)

Answer:

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
