P=Fv
K.E = 1/2 mv2
The Attempt at a Solution
This is the examiner report:
Why infinite acceleration? Is it because the mass is too small?the kinetic energy of the sand does increase by 1/2 mv2 but this cannot be the only power involved (it would imply an infinite acceleration for every grain of sand landing on the belt)
