Description: A 20-kg crate is subjected to a force having a constant direction and a magnitude $F = 100\text{ N}$ applied at $30°$ above the horizontal. When $s = 15\text{ m}$, the crate is moving to the right with a speed of $8\text{ m/s}$. Determine its speed when $s = 25\text{ m}$. The coefficient of kinetic friction between the crate and the ground is $\mu_k = 0.25$.
