Question
Starting from rest, Jack
and Jill skateboard down
a hill as shown in the
sketch. Assume that
friction and air resistance
are negligible. Jack has
more mass than Jill and
rides steeper side, but
their height of descent is same.
(a) Is the speed at the bottom of the hill greater for Jack, greater for Jill, or the same for
both? Derive the speed using conservation of Energy.
(b) Is the kinetic energy at the bottom of the hill greater for Jack, greater for Jill, or the
same for both? Explain using supporting equation.
(c) Is the work done by the gravitational force greater for Jack, greater for Jill, or the same for both? Explain using supporting equation.
