When gasoline is burned in the cylinder of an engine, it creates a high pressure that pushes on the piston. If the pressure is 100 pound-force per square inch [psi], and it moves the 4-inch [in] diameter piston a distance of 5 centimeters [cm] in 0.2 seconds [s], how much horsepower [hp] does this action produce?
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?
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].
