Pressure1.) A cat’s paw applies 72N on a cat flap for it to open and the paw is roughly 6cm2. What pressure does the cat’s paw exert on the cat flap?

2.) A boy in a karate class either kicks or shoves another boy with a force of 270N. The boys foot has an approximate area of 180cm2 and his hand is 160cm2 Was it a kick with his foot or a shove with his hand if the pressure applied is 1.5N/cm2?

A garden centre sells 3 types of square based sheds in a garden centre. One is 4m, one is 5m and the other 6m. What force does each shed apply on the ground if they all apply a pressure of 35N/m2?

A:

B:

C:

The force is calculated by using the formula: Force = Weight in kg x 9.8. What does each shed weigh?

4.) At what force does a finger press a doorbell if the pressure is 5.2N/cm2 and the area of my finger in contact with the button is 2cm2?

5.) The area of the sole of my foot that is in contact with the ground is 80cm2. If the force I exert on the ground is 550N. What pressure do I apply to the ground when both of my feet are on the ground?

6.) A box lying on the table applies a pressure of 30N/m2 on the table. What is the volume of the box if the box is 0.5m in height and applies a force of 18N?
