Q1. A car in stop-and-go traffic starts at rest, moves forward 18 in 8, and then comes to rest again. What distance does the car cover in the first 4.0 seconds of its motion?

Q2. The distance to the Andromeda Galaxy is estimated at about 2 ´ 106 light years. A light year is distance travelled by light in one year; if the speed of light is 3 ´ 108 m/s, about how far is it from our galaxy to Andromeda? (1 year = 3.15 ´ 107 s)
