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

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
