Units and Calcs: Mechanics

How many joules of energy does a crank toy produce if it generates 5N of force over 10s while it travels 3m?

How much energy does a cyclist produce if they can power a 60-Watt lightbulb for 45 seconds?

Nutritional information is often listed in Calories where 1 Cal = 4184 J. If a cookie contains 100 Cal what distance would someone need to run to expend the same number of calories in a single cookie if they produce an average force of 50 N while running?

How much energy does my dog produce while running for 10 minutes if she produces 20 W of power while running?

How much power does a lightbulb produce if it expends 260 J in 13 s?

The Pascal (Pa) is the SI unit of pressure which can be further broken down into the units N/m². Given this information how much work does a gas at 200 Pa do while at 56K if it has a 20 L change in volume (Note: 1 m³ = 1,000 L)?

In physics, the area under the curve can represent the multiplication of the two axes. For example, the force x distance graph shown below would represent work.

Given this information which of the following units can be used to represent the area under the curve for the graph above?

I. W x s
II. Nm
III. J

The wheels of a skateboard encounter 40 N of frictional force as they roll along at a constant velocity of 6 m/s. How much power must the rider of the skateboard produce in order to keep the skateboard at a constant velocity of 6 m/s?
