If an object has a mass of 14 kg, what is it’s weight

Alex_Xolod [135]

Answer:

Weight = 137.2 kg.m/ $s^{2}$

Explanation:

Given

mass of an object, m = 14 kg

Weight (W) is given by the formula:

W = mg , where m is mass of the object and g is acceleration due to gravity and the value is 9.8 m/ $s^{2}$

Hence W = 14 kg x 9.8 m/ $s^{2}$

= 137.2 kg.m/ $s^{2}$
