Answer:

3×10⁵ N/m²

Explanation:

From the question given above, the following data were obtained:

Force (F) = 450 N

Area (A) = 0.0015 m²

Pressure (P) =?

Pressure is simply defined as the force per unit area. Mathematically, it is expressed as:

Pressure (P) = Force (F) / Area (A)

P = F/A

With the above formula, we can obtain the pressure exerted by the man on the ground. This can be obtained as follow:

Force (F) = 450 N

Area (A) = 0.0015 m²

Pressure (P) =?

P = F/A

P = 450 /0.0015

P = 3×10⁵ N/m²

Thus, the pressure exerted by the man on the ground is 3×10⁵ N/m².
