With one paddler on board a canoe sits in the water as shown in the above cross-section. If the canoe is 4 m long and can be treated as though it were rectangular in planform when viewed from above, calculate the maximum height that the centre of gravity of the canoe and paddler combined can be above the bottom of the canoe in order for the canoe to remain stable.

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
