    Both of them will have same kinetic energy.

    Explanation: Kinetic energy is the energy of motion, every object in motion posses some kinetic energy. Kinetic energy can be calculated by the given formula,

    i. e, K. E = 1/2 mv².

    Where, K. E is kinetic energy,

    m is mass of the object

    v is the velocity of the object

    On observing the formula we can state that K. E is directly proportional to mass (m) and velocity (v) of the object. Obviously, birds have more mass than bees but in question it has given 10 Kg of bees and 10 Kg of birds which means mass is same and also both of them are travelling with same velocity i. e 10m/s and hence both of them will have same kinetic energy (as both of the variables i. e m and v are same).

    Result: Both bees and birds have same kinetic energy.
