Q4. An 80 kg dog is lying on the floor at rest. The coefficient of kinetic friction between the dog and the floor is μ = 0.2. Ignore static friction. If the dog is pulled by a person with a 200 N force as shown, determine the speed of the dog when t = 3 s. [Do NOT use the equations of motion i.e. Σ F = ma, directly; otherwise your solution to this qustion will receive a zero]. 60⁰ P-200 N
