Tim got a huge birthday gift from his grandmother. A 400. N crate has been delivered to his driveway. In order to get it started moving toward his door, he has to push it with a horizontal force of 250 N, but as soon as it is moving, he can keep it moving at a constant speed by pushing with a 120 N force. What are the coefficients of static and kinetic friction of Tim's birthday gift and the driveway?
