    41.3 m/s^2 option (e)

    Explanation:

    force, F = 6.81 N

    mass, m = 165 g = 0.165 kg

    Let a be the acceleration of the puck.

    Use newtons' second law

    Force = mass x acceleration

    6.81 = 0.165 x a

    a = 41.27 m/s^2

    a = 41.3 m/s^2

    Thus, the acceleration of the puck is 41.3 m/s^2.
