Willy Wonka is in court for running a red light (675 nm). He tells the judge that it was indeed, a green light (540 nm). Calculate how fast Willy Wonka was driving so we can put him in jail in the name of physics.

Many people have some sense for the SI units describing mass, length, and time. one kilogram is roughly the mass of a typical sports water bottle (when full) one meter is roughly the height of a kitchen counter one second is a typical time interval between heartbeats (when at rest) But the momentum unit we just learned—the "kilogram meter per second"—is another matter! How many kg · m/s might describe the following everyday phenomena? (Recall that momentum equals the product of mass and velocity.) a 0.05 kg (50-gram) tennis ball crossing the court at 20 m/s (about 45 mph) _____________ kg · m/s a 50 kg (110-pound) teenager jogging at 2 m/s    about 4 1 2  mph   .  _______________kg · m/s a two-ton SUV (2,000 kg) following a dirt road at 5 m/s (about 11 mph).  ________________kg · m/s

If a m = 81.1 kg person were traveling at v = 0.980c, where c is the speed of light, what would be the ratio of the person's relativistic kinetic energy to the person's classical kinetic energy? kinetic energy ratio: What is the ratio of the person's relativistic momentum to the person's classical momentum? momentum ratio:

A spacecraft is traveling at ~v = 38.4km s (yes, that is a reasonable speed for a rocket). How long will it take to travel from the earth to the moon, a distance of 384 Mm from Earth?

This Cannot be hand-drawn, this physics solution must be typed out, and the explanation in the simplest manner.

Based on a grade 11 physics student, answer the following question:The rebels are fighting the imperials on the icy planet Hoth. Han Solo didn’t dress for the weather (this ain’t Tattooine bud!), and is frozen solid (1234 kg of ice, at -123˚C ). Fortunately for Han, an AT-AT walker shoots its blasters and misses its target but hits Han which vaporizes the ice and brings him to a piping 102˚C. How much heat was added to Han Solo to turn him from a frozen chunk into a ‘Luke-warm’ rebel?

How might I answer Problem 4 in my Electromagnetism problem? In this course, we've used advanced math like Calculus 3 in order to compute things out. Before I quote Problem 4, I would need to quote Problem 3 because Problem 4 is an extension of 3. 3 reads, "Suppose you're at rest in the lab frame and an electron is moving along the x-direction at a speed of .999c. Compute its magnetic field in the lab frame." Now, Problem 4 reads, "What is the electric field that the lab observer sees for the electron in Problem 3?" I have some pictures that may help. I think that it's confusing because I'm thinking about what I would see vs. what an electron would see. In my notes, I have O', but I'm not sure if that is for the electron.
