Answer: 637N
Explanation:
Force needed to lift box = ?
Mass of box = 65kg
Acceleration due to gravity, g = 9.8m/s2
Recall that Force applied depends on the mass of an object moved against gravity.
Thus, Force = Mass x acceleration due to gravity
F = mg
F = 65kg x 9.8m/s2
F = 637N
Thus, 637 newton of force is needed to lift a 65kg box
