At time t = 0, the hockey puck is sent sliding over a frozen lake, directly into a strong wind. Gives the velocity v of the puck versus time as puck moves along a single axis. (The time axis is marked in increments of 0.25 s.) At t = 2.8 s, what i..
A transparent oil with index of refraction 1.29 spills on the surface of water (index of refraction 1.33), producing a maximum of reflection with generally incident red light (wavelength 700 nm in air). Assuming the maximum occurs in the first order;..
A man is running at speed c (much less than the speed of light) to catch a bus already at a stop. At t=0, while he is a distance b from the door to the bus, the bus starts moving with the positive acceleration a.
