Did you know that in physics, work is defined as the transfer of energy that occurs when a force is applied to an object that causes it to move? In the given scenario, the nurse is carrying a 3.0 kg newborn child at a height of 1.2 m off the floor and carrying the baby along a hospital corridor of 1.5 m. To calculate the work done by the nurse on the baby, we need to multiply the force applied by the distance moved. Since the baby is being carried horizontally, the force applied in the vertical direction is the weight of the baby, which is equal to its mass times the acceleration due to gravity. In this case, the work done by the nurse on the baby would be zero, because the baby is not being lifted or displaced vertically. The only work being done is in carrying the baby horizontally, which is equal to the horizontal force applied by the nurse multiplied by the distance moved.
