8. The figure below shows the top view of a positively charged rod. The points X, Y, W, and Z lie in the same plane near the rod. Points W and Y are equidistant to the rod and points X and Z are equidistant to the rod, as well. a. Is the work done by the electric field on a positive charge as it moves from W to X along the straight-line path shown positive, negative or zero? Explain. Hint: Remember how Work was defined in PHYS 221. W X b. Is the work done by the electric field on a positive charge as it moves from X to Z along the circular arc shown positive, negative or zero? Explain.

I solved for part a and part b which asked part a) The plane flies at 554 miles per hour, relative to the skyscraper. If Casey throws the ball to Matt at 23 miles per hour, relative to the plane, then what speed will Myles see the ball move at? (I got speed of 577 miles per hour). For part b they asked "Matt subsequently tosses the ball back to Casey, at 25 miles per hour. What speed does Myles see the ball move at? (I got 529 mph) now I need help with part c and part d. part c) Lets's imagine that instead of an airplane, Casey and Matt are on a rocketship, traveling at 93% of the speed of light. Additionally, Casey and Matt have been training very hard and so can toss the ball incredibly fast. If Casey throws the ball to Matt at 25% of the speed of light, relative to the rocket, then what speed will Myles see the ball move at? part d) Did you use Galilean Relativity or Special Relativity to compute the speeds in part a-c? Why did you choose to use the equation you chose for each…

Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU = 150,000,000 kilometers. a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation: 150000000000 meters How else might you express this number? (Millions, billions, etc. ?) b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to the Sun? (Assuming you have a car that works in outer space.) Use the equation distance = velocity x time, or time = distance / velocity. Time = distance/velocity = , seconds (don't forget to use scientific notation.)
