A 20.0kg crate is subjected to a constant force of 100 N as shown in the figure. When the distance it is pulled is s = 15.0 m the crate is moving at 8.0 m/s. Determine its speed when s = 25 m. The coefficient of kinetic friction between the crate and the ground is 0.25. Use the principle of work and energy. 30
