Explanation Given: The height ( h ) of the table. The weight ( W ) of the suitcase. The time ( t ) the lifting takes. Formula used: The power ( P ) supplied on the suitcase to lift it is defined as: P = W t = | F → | . | Δ x → | . cos ( θ ) t (1) Where: | F → | is the magnitude of the force applied on the suitcase. | Δ x → | is the magnitude of displacement. θ is the angle between the force and displacement
