To solve this problem we will consider the concepts related to the normal deformation on a surface, generated when the change in length is taken per unit of established length, that is, the division between the longitudinal fraction gained or lost, over the initial length. In general mode this normal deformation can be defined as
Here,
= Change in final length 
and the initial length 
PART A)
PART B)
PART C)
Therefore the rank of this deformation would be B>C>A
The work that Sam should do in order to stop is the boat is the same as that of the kinetic energy of the object in order to counter its motion. Kinetic energy is calculated through the equation,
KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity.
Substituting,
KE = 0.5(1200kg)(1.2 m/s)²
<em>KE = 864 J</em>
I think the correct answer from the choices listed above is option C. The change in the statement that would make a more powerful goal would be to make <span>it measurable by explaining how far away the target is. Hope this answers the question. Have a nice day.</span>
