A robot is exploring Charon, the dwarf planet Pluto's largest moon. Gravity on Charon is 0.278 meters per second [m/s2]. During its investigations, the robot picks up a small spherical rock for inspection. The rock has a diameter of 6 centimeters [cm] and is lifted 16 centimeters [cm] above the surface. The specific gravity of the rock is 10.7. The mechanism lifting the rock is powered by a 9-volt [V] power supply and draws 1.09 milliamperes [mA] of current. It requires 13 seconds [s] to perform this lifting task. What is the efficiency of the robot?
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?
If a ball is dropped from a height (H) its velocity will increase until it hits the ground (assuming that aerodynamic drag due to the air is negligible). During its fall, its initial potential energy is converted into kinetic energy. If the ball is dropped from a height of 680 centimeters [cm], and the impact velocity is 38 feet per second [ft/s], determine the value of gravity in units of meters per second squared [m/s2].

- NASA sent a probe to Saturn's moon Titan, where the acceleration due to gravity is 1.4 meters per second squared [ms2]. Titan's atmospheric pressure is 1.3 times Earth's atmospheric pressure at sea level. The probe landed in a lake of liquid methane, which has a density of 0.454 kilograms per liter [kgL]. Since the probe weighs 300 pounds-force [lbf] on Titan and has a volume of only 1.2 cubic feet [ft3], it immediately sank. It now sits 65 feet [ft] below the surface of the lake.
