Hmm, im from combine, the easier explanation is that
gravatational pull is at 10m/s. thus they should reach at the same
time
and becos of the weight they contain diff amount of
gravitational potential energy, so the force that they reach the
ground will be larger.
im not very sure though
potential energy is mgh. so bigger the mass, the higher the P.E.
but nope, that's not the right... have to stick with the more
complicated explanation
