a. Explain what is meant by the centre of gravity of an object.
b. A flagpole of mass 25 kg is held in a horizontal position by a cable as shown. The centre of gravity of the flagpole is at a distance of 1.5 m from the fixed end.
i. Write an equation to represent taking moments about the left-hand end of the flagpole. Use your equation to find the tension T in the cable.
ii. Determine the vertical component of the force at the left-hand end of the flagpole.
