Answer: correct option is C
The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.
Step-by-step explanation:
The total work done = P.E + K.E
K.E = 1/2mv^2
The speed V depends on the position:
0 < x < 5
Also, since work done = F × distance x
The workdone also depends on F(x)
The net force = 0 that is
F + fr = 0
Where fr = frictional force.
Therefore the best option for the hypothesis of work done will be;
The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.
