7. Imagine that the coefficient of kinetic friction between a certain 15-kg box and the floor is 0.35. How hard would you have to push on it to move it at a constant speed of 2.6 m/s across the floor?

The force will not depend upon speed, as long as the speed is constant.
The required force is
M*g*(mu_k) newtons
mu_k is the kinetic friction coefficient.
