1. A car accelerates from 12 m/s to 25 m/s in 5.0s. What was its acceleration? How far did it travel in this time? Assume constant acceleration.

2. if you used only a keyboard to enter data, how many years would it take to fill up the hard drive in a computer that can store 1.0 terabytes  of data? Assume 35-hour work weeks, and that you can type 180 characters per minute, and that one byte is one keyboard character.

3. Two locomotives approach each other on parallel tracks. Each has a speed of 150 km/h with respect to the ground. If they are initially 9.5 km apart, how long will it be before they reach each other?

Hint: use a common variable that the two locomotives share.
