A robotic rover on Mars finds a spherical rock with a diameter of 10 centimeters [cm]. The rover picks up the rock and lifts it 25
centimeters [cm] straight up. The rock has a specific gravity of 4.65. The gravitational acceleration on Mars is 3.7 meters per second
squared [m/s]. If the robot's lifting arm has an efficiency of 30% and required 13 seconds [s] to raise the rock 25 centimeters [cm],
how much power in units of watts [W] did the arm use?

A tank in the shape of a right circular cone, apex down, is filled with olive oil weighing 45lbs/ft^3. If the tank is 5 feet high and 4 feet in diameter across the top, how much work is required to pump the olive oil out of the top of the tank?
A conveyor belt uses 5 newtons [N] of force to move a 34 kilogram [kg] box to a velocity of 2.05 meters per second [m/s] over the length of the conveyor. If you assume all work by the conveyor belt is transferred to the kinetic energy of the box, how long is the conveyor belt in units of feet [ft]?

Assume that they have a mass of 97.4 kg.arrow_forwardYour answer is partially correct. The summit of a mountain is 5540 m above sea level. (a) How much energy would a 87 kg climber expend against the gravitational force on him in climbing to the summit from sea level? (b) How many candy bars, at 2.13 MJ per bar, would supply an energy equivalent to this? Your answer should suggest that work done against the gravitational force is a very small part of the energy expended in climbing a mountain.
