Question

Mother placed a trunk of books weighing 5,000 N on the floor. The area of the base of the trunk was
2.5 m². How much pressure did it exert on the floor?
2. A statue has a base which is 10 cm x 10 cm = 0.01 m², and exerts a pressure of 500 N/m². What is
its weight?
3. A motorcycle weighs 4,500 N. If the pressure the tyres exert on the road is 1,000,000 Pa, what is the
area of each tyre in contact with the road? (Remember that a motorcycle has two tyres.)
4. A box is 5 cm x 5 cm x 5 cm in size. How much does it weigh when it creates a pressure of 7,500 Pa
on the floor?
5. A box applies a force of 100 N on a base of Im? What pressure does it apply to the area?

Answer 1

Thus the weight of the statue is 0.5 Kg

Explanation:

Question statement:

A statue has a base which is 10 cm x 10 cm = 0.01 m², and exerts a pressure of 500 N/m². What is  its weight?

Solution:

We know that:

F = P x A

F = 500 [N / m^2] x  0.01 [m^2]

F  = 5 N

Now by using Newton’s Second Law:

F = m x a = m x g

Solve for m:

m = F / g

We know that g = 10 [m/s^2]

m = 5  / 10 = 0.5 kg

Thus the weight of the statue is 0.5 Kg
