(a)  

Answer explanation

What would the pressure be when a 5000 N force is exerted on an area of 33.33 m²?

(a)  

Answer explanation

What would the pressure be when a 85 kg man stands on the ground and the surface area of each shoe is 0.325 m²?

Give your answer to 1 decimal place.

(a)  

Answer explanation

Find the area by doubling 0.325 to 0.65 as the man wears two shoes.

The question gives us his mass as 85 kg, but mass is a scalar quantity, not a force. Convert to a force using W = m x g to get his weight as 850 N.

p = F/A

p = 850 N / 0.65 m²

p = 1307.7 Pa (to 1dp)

What would the pressure be when a 4000 N force is exerted on an area of 0.02 m²?
