Answer:
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
Explanation:
The pressure is determined by the definition of stress, which is the force exerted by the buggy on the martian surface divided by the contact area of the latter:
[tex]\sigma = \frac{F}{A}[/tex]
Where:
[tex]\sigma[/tex] - Stress, measured in pascals.
[tex]F[/tex] - Force, measured in newtons.
[tex]A[/tex] - Area, measured in square meters.
The force is the weight of the buggy (40 N) and [tex]A = 0.025\,m^{2}[/tex], the stress is now calculated:
[tex]\sigma = \frac{40\,N}{0.025\,m^{2}}[/tex]
[tex]\sigma = 1600\,Pa[/tex]
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
