Q1. A 57 kg student sits on a chair which is solely supported by a solid 1/2 meter long steel rod 1cm in diameter. To the nearest micron (millionth of a meter) what is the change in length of the rod produced by the student's weight?

Q2. To pass a physical education class at a university, a student must run 1.0 mi in 12 min. After running for 12 min, she still has 510 yd to go. If her maximum acceleration is 0.15 m/s2, can she make it? If the reply is no, determine what acceleration she would need to be successful.
