The force used to lift the object must be greater than 45 N and direction of the force applied to lift the object is upward since the object will move upwards when it is lifted.
The given parameters;
- weight of the object, W = 45 N
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of the mass and the acceleration of the object.
The object always move in the direction of the applied force.
Thus, we can conclude that the force used to lift the object must be greater than 45 N and direction of the force applied to lift the object is upward since the object will move upwards when it is lifted.
