First write down all your known variables:
vi = 25m/s
a = 7.0m/s^2
t = 6.0s
vf = ?
Then choose the kinematic equation that relates all the variables and solve for the unknown variable:
vf = vi + at
vf = (25) + (7.0)(6.0)
vf = 67m/s
The final velocity of the motorcycle is 67m/s.
Friction would inhibit your speed and maximum work potential so, friction is the answer.

I think the answer is b, energy.
Answer:
Work done to lift the box is 515.03 J
Explanation:
By work energy theorem we know that work done by all forces is equal to change in kinetic energy
So we have

so we have

so we have
