Ask AI: A robotic arm lifts a stack of cafeteria trays weighing 62 newtons (N). It moves the trays 2 meters (m). How much work has the robotic arm performed?

Work is calculated as the product of force (in this case, the weight of the trays) and the distance over which the force is applied. The formula for work (W) is W = Fd, where 'F' represents the force and 'd' represents the distance. Given that the force (F) is 62 newtons (N) and the distance (d) is 2 meters (m), you can substitute these values into the formula: W = Fd W = 62N * 2m W = 124 Joules So the robotic arm has performed 124 Joules of work.
