Question: What is the weight in newtons of an object that has a mass of (a) 8 kg, (b) 0.04 kg, and (c) 760 Mg? Answer: (a) For mass, "= 8kg Calculate the weight of the object using the following equation: W=mg () Here, m is the mass of the object, and g is acceleration due to gravity. Substitute 8kg form ang 9-81m/s" for g in the equation (1). W=8x9.81 = 78.48 kg-m/s’ =78.48 kg-m/s’ x IN _ 1 kg-m/s° = 7848 N Therefore, the weight of the object is 78.48 N . (b) For mass, = 0.04 kg te Substitute 9.04 kg for mang 9-81 nvs" forg in the equation (1).
