The weight of the buggy was 40N on Mars. When the buggy landed on Mars it rested on an area of 0.025 m2. Calculate the pressure

elena-s [515]

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:

$\sigma = \frac{F}{A}$

Where:

$\sigma$ - Stress, measured in pascals.

$F$ - Force, measured in newtons.

$A$ - Area, measured in square meters.

The force is the weight of the buggy (40 N) and $A = 0.025\,m^{2}$ , the stress is now calculated:

$\sigma = \frac{40\,N}{0.025\,m^{2}}$

$\sigma = 1600\,Pa$

The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
