frictionless car is released from rest on a track has a fan on top that pushes with a force of 1.3 Newtons and the mass of the car is 333 grams. A second car has a mass of 250 grams and is also released from rest with the same fan pushing it. Suppose you want the two cars to travel a distance of 2.0 meters and arrive at the same time. You can do this by adding a second fan to the second car. What magnitude of force (and in what direction) should this second fan be
