Q1. In a head-on collision, a car stops in 0.24 from a speed of 25. The driver has a mass of 74, and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fraction of a second?

Q2. A 550N physics students stand on a bathroom scale in an 850 kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 450N. (a) Find the acceleration of the elevator (magnitude and direction). (b) What is acceleration if the scale reads 670N? (c) If the scale reads zero, must the student worry? Explain (d) what is the tension in the cable in parts (a) and (c)?

Q3. A double-slit interference pattern is created by two narrow slits spaced 0.20 mm apart. The distance between the first and fifth minimum on a screen 60 cm behind the slits is 6.0 mm. What is the wavelength of the light used in this experiment?
