Design a fuzzy cruise-controller for your car with the foll speed: accelerator-pressure: range: 0-100% range: 0 -140 km/h rules: 1. if the speed is slow, accelerat is high or_pressure 2. if speed is right, then no change. 3. if motor speed is fast, accelerator_p ressure is low. for speed of 100 km/h what is the acceler ator_pressure?

Arailroad car collides with and sticks to an identical railroad car that is initially at rest. after the collision, the total kinetic energy of the two cars is a) the same as before. b) half as much as before. c) one third as much as before. d) one fourth as much as before. e) twice as much as before.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?

If you let go of the notebook after lifting it, will it move? how?
