David Sang and Darrell Hamilton Solutions for Chapter: Forces and Matter, Exercise 4: Exercise 5.3

Calculate the pressure in $\mathrm{Pa}$ when a force of $200 \mathrm{N}$ presses on an area of $0.40 {\mathrm{m}}^2$

The pressure inside a car tyre is $250 \mathrm{kPa} (250000 \mathrm{Pa})$. Calculate the total force in newton that is exerted on the inner surface of the tyre if its surface area is $0.64 {\mathrm{m}}^2$.

The Rocket in the figure is $111 \mathrm{m}$ high and a mass of $3100000 \mathrm{kg}$. Explain how the vehicle transporting it is adapted to carry such a load.
