Answer and step-by-step explanation:
To find Mr. Colina's weight, we must use the formula:
W = mg
where
W is the weight of the object/person,
m is the mass of the object/person, and
g is the acceleration of gravity.
Let's substitute the given values to the formula.
m = 78.9kg
g = 9.8m/s^2
*The acceleration of gravity of the Earth is always the same which is 9.807 m/s^2 and just round it off to the nearest tenths.
W = 78.9kg × 9.8m/s^2
W = 773.22 (kg)(m/s^2)
W = 773.22N
*N is the unit for Newtons.
Therefore, Mr. Colina's weight is 773.22N.
