Q1. A particle travels counter clockwise around the origin at constant speed in the circular path that has a diameter of 2.50 m, going around twice per second. Point Q is on the path halfway between points P and R that lie on the x axis and the y axis, respectively. State the following velocities as vectors in polar notation. (a) What is the particle's average velocity over the interval PR? (b) What is its average velocity over interval PQ? (c) What is its instantaneous velocity at point P?

Q2. A light beam from a 2.10 m W He-Ne laser has a wavelength of 633 nm. How many photons does the laser emit in one second? (h = 6.626 × 10-34 J · s, c = 3.00 × 10^8 m/s)
