m = 5 kg.
g = 9.8 m / s ^ 2.
F = 60 N.
Frav -?
Two forces act on the body: the force of gravity m * g, directed vertically downward, and the force F, directed vertically upward.
The resultant Frav of these two forces will be determined by the vector sum: Frav = F + m * g.
Since the forces are directed in opposite directions, the resultant force Frav will be directed towards the greater force and its modulus will be determined by the formula: Frav = F – m * g.
Frav = 60 N – 5 kg * 9.8 m / s ^ 2 = 11 N.
Answer: the resultant force Frav will be directed vertically upwards and is equal to Frav = 11 N.
