A force due to gravity on a body is
. This body has to be
lifted to the height
using a slope. The maximal force which can be used to lift the body is
.
Neglect the friction and find the minimal length of the slope required to accomplish
this task.Hint: The force due to gravity can be decomposed into two directions. The normal force
is compensated by the reaction
of the slope. The force
parallel to the slope is required to overcome if we wish to lift the body (see the picture).
