**Question1**

A space station is in the shape of a hollow ring, 450 in diameter. At how many revolutions per minute must it rotate in order to simulate Earth's gravity-that is, so that the normal force on an astronaut at the outer edge would be the astronaut's weight on Earth?

**Question2**

The driver of a 1800 car travelling on a horizontal road at 114 rapidly applies the brakes. Due to a slippery pavement, the friction of the road on the tires of the car, which is what slows down the car, is 26.0 of the weight of the car.

**Question3**
