Answer:
Machine - A device consisting of fixed and moving parts that modifies mechanical energy and transmits it in a more useful form.
Mechanical advantage - Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
Inclined Plane - A plane set at an angle to the horizontal, especially a simple machine used to raise or lower a load by rolling or sliding.
Wedge - A piece of material, such as metal or wood, thick at one edge and tapered to a thin edge at the other for insertion in a narrow crevice, used for splitting, tightening, securing, or levering.
Screw - A cylindrical rod incised with one or more helical or advancing spiral threads, as a lead screw or worm screw.

Answer: 13.6 N
Explanation:
The equation of motion for the rabbit is:
(1)
Where:
is the distance traveled by the rabbit
is the rabbit's initial velocity, assuming it started from rest
is the time
is the acceleration
Isolating
:
(2)
(3)
(4)
On the other hand, the force
is given by:
(5)
Where
is the mass of the rabbit
Substituting (4) in (5):
(6)
Finally:
