Question

1. Pressure

As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of

2.0 cm² and the woman’s mass is 50.0 kg. Express the pressure in Pa.

2. Pressure in a fluid: Landing on Venus

One of great difficulties in landing on Venus is dealing with the crushing pressure of the atmosphere, which is 92 times the earth’s atmospheric pressure.

1. If you are designing a lander for Venus in the shape of a hemisphere 2.5 m in diameter, how many newtons of inward force must it be prepared to withstand due to Venusian atmosphere? (You must consider both the top curved surface and the flat bottom surface).
2. How much force would the lander have to withstand on the earth?
