Question: The crate, which has a mass of 100 kg, is subjected to the action of the two forces. If it is originally at rest, determine the distance it slides in order to attain a speed of 6 m/s. The coefficient of kinetic friction between the crate and the surface is μ = 0.2.

Problem 14-3 from:

Engineering Mechanics: Dynamics, 14th edition
Russell C. Hibbeler

Thank you guys for watching.

We can also use v²=u²+2as can't we?

Excuse me sir, we know that friction force=µkN, and that force acts in x-axis, but why can't we use the equation ΣFx=0 to find the value of normal force? Can you explain it please?
