Arobotic rover on mars finds a spherical rock with a diameter of 12 centimeters [cm]. the rover picks up the rock and lifts it 25 centimeters [cm] straight up. the rock has a specific gravity of 5.25. the gravitational acceleration on mars is 3.7 meters per second squared [m divided by s squared]. if the robot's lifting arm has an efficiency of 45% and required 12 seconds [s] to raise the rock 25 centimeters [cm], how much power in units of watts [w] did the arm use?
