A robotic rover on Mars finds a spherical rock with a diameter of 8 centimeters [cm]. The rover picks up the rock and lifts it 25 centimeters [cm] straight up. The rock has a specific gravity of 4.75. The gravitational acceleration on Mars is 3.7 meters per second squared [m/s²]. If the robot's lifting arm has an efficiency of 35% and required 10 seconds [s] to raise the rock 25 centimeters [cm], how much power in units of watts [W] did the arm use?
