SUMMARY
The net force acting on a 5kg suitcase when lifted with a force of 60N is calculated by subtracting the gravitational force of 49N (derived from 5kg multiplied by 9.8m/s²) from the applied force. This results in a net force of 11N directed upwards. Consequently, using the equation ma, the acceleration of the suitcase is determined to be 2.2 m/s² in the upward direction.
