    294 Joules

    Explanation:

    From the question;

    Mass of the drum is 10 kg The length of inclined surface, OA is 5 m The final height of the drum on the plane AB is 3 m

    We are required to determine the potential energy of the drum at A

    We know that potential energy is given by the formula;

    Potential energy = mgh

    where m is the mass, g is the gravitational pull and h is the height

    Taking g as 9.8 N/kg

    Then;

    Potential energy = 10 kg * 9.8 N/kg * 3 m

    = 294 Joules

    Thus, the potential energy of the drum at A is 294 Joules
