Answer 2

Calculating Pressure Exerted by the Box

To calculate the pressure exerted by the box on the ground, we can use the formula:

Pressure = Force / Area

Where: - Force = mass * acceleration due to gravity - Area = area of the bottom of the box

Given: - Mass (m) = 31 kg - Acceleration due to gravity (g) = 9.8 m/s^2 - Area (A) = 400 cm^2 = 0.04 m^2

First, let's calculate the force exerted by the box on the ground:

Force = mass * acceleration due to gravity Force = 31 kg * 9.8 m/s^2 Force = 303.8 N

Now, we can calculate the pressure:

Pressure = Force / Area Pressure = 303.8 N / 0.04 m^2 Pressure = 7595 Pa

So, the pressure exerted by the box on the ground is 7595 Pascal.
