| September 16, 2021 | education
Ft = 1.69 N.
g = 9.8 m / s ^ 2.
m -?
The force of gravity Ft is the force with which the earth attracts all bodies that are on its surface, due to the law of universal gravitation and is determined by the formula: Ft = m * g.
Where m is body mass, g is gravitational acceleration.
m = Fт / g.
m = 1.69 N / 9.8 m / s ^ 2 = 0.173 kg.
Answer: the body has a mass m = 0.173 kg.
