Car a is traveling at a constant speed 90 m/s east. a second car b is initially at rest when car a passes it at t=0. if car b starts immediately to chase car a at t=0, and catches car a at t=25 s, what was car b's acceleration (assume a constant acceleration)?

Answer(a)   the matererials that are in contact, the two materials and the nature of their surfaces/// (b)/// the force pushing the two surfaces together, pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other

34 degrees fahrenheit
