2. A 300 kg crate is pulled starting from rest by a motor and a pulley...
Prompt: A 42.0-kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 225 N. For the first 11.0 m the floor is frictionless, and for the next 10.0 m the coefficient of friction is 0.20. Question: What is the final speed of the crate after being pulled these 21.0 m?
