Answer:
Weight of the Jaden on earth is 490 N.
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .
Gravity on Earth is 9.8 m/s² .
Jaden’s mass is 50 kilograms.
g = 9.8 m /s²
m = 50
Put the values in the formula
Thus
w = 50 × 9.8
= 490 kg m /s²
(As N = kg m/ s²)
= 490 N
Therefore the weight of the Jaden on earth is 490 N.
