Question

The weight of a boy on the surface of the earth is 294n. Find his mass

Answer 1

• Answer:  Explanation: weight = mass × acceleration due to gravity                       W= mg              Weight is given as 294N              Acceleration due to gravity is 9.8m/ s^2                  Therefore m= W/g                                    m = 294/9.8 = 30kg Hope you understand...  

Answer 2

Explanation:

w = m*g

here w= 284 n given

mass is constant any where in universe

but weight varies because g varies

g = 9.8 m/s for calculation we could assume it as 10

m= w/g

ie

294/10

29.4 answer

taking near value

its 30 is the answer
