the value of kinetic energy is 9.9 J.
given:
1)mass of the pupil = 55 kg
2)velocity of the pupil = 0.6m/s
kinetic energy is defined as the energy possed by a body
now since the velocity is constant and we know the mass of the pupil
and velocity of the pupil,
we can find the kinetic energy of pupil using the formula for kinetic energy
i.e. kinetic energy = 0.5×mass×velocity
therefore,
the kinetic energy of pupil = 0.5×55×0.6
the kinetic energy of pupil = 9.9 J
