a 70g bag of potato chips contains 1.6MJ of energy. Working at your maximum power, how long would it take to burn this energy?

To calculate the time it would take to burn the energy contained in the potato chips, we need to use the concept of power. Power is defined as the rate at which energy is generated or consumed, and is typically measured in watts (W).

In this case, the power at which you are working is not provided. However, if we assume that you are working at your maximum power, we can substitute it with a reasonable value. Let's say a person's maximum sustainable power output is around 100 watts (W).

The equation that relates power (P), energy (E), and time (t) is:

E = P * t

We need to rearrange this equation to solve for time (t):

t = E / P

Now we can plug in the values we have:

E = 1.6 MJ (1 MJ = 1,000,000 joules)
P = 100 W

First, let's convert 1.6 MJ to joules:

1.6 MJ = 1.6 * 1,000,000 J = 1,600,000 J

Now we can calculate the time it would take to burn this energy:

t = 1,600,000 J / 100 W = 16,000 seconds

Since time is in seconds, let's convert it to a more common unit:

16,000 seconds = 4 hours and 26 minutes (approximately)

Therefore, it would take approximately 4 hours and 26 minutes to burn the energy contained in a 70g bag of potato chips while working at your assumed maximum power.
