A car and a truck are moving in opposite directions on an isolated two lane highway. At t = 0, the truck and car are at the same location (x = 0) along the x-axis. Assume the positive x-direction is rightward. See schematic below. At t=0, the truck's velocity is +10.0 m/s. The truck is speeding up with acceleration +3.0 m/s². At t = 0, the car's velocity -15.0 m/s. The car is slowing down with acceleration +5.0 m/s². Show all work clearly. (a) (20) What is the DISTANCE between the car and truck when the car momentarily comes to rest? (b) (15) What is the velocity of the truck when the car comes to rest? (c) (5) What is the speed of each relative to the other at t = 2.0 seconds? -15 m/s + 10 m/s

The star Alpha Centauri is 4.367 light vears from earth. What velocity do you need to travel at to reach this star in 1,447 years. Give your answer as a fraction of the speed of light (e.g. 0.406 for 0.406c) Round your answer to 3 decimal places. Add your answer Question 8 An electron is accelerated accross a voltage of 344kV. What is the momentuum of the electron? Use a value for the electron masss of 511 kevic. Give your answer in units of keWc (eg if the answer is 350 kevic write 350I Round your answer to 0 decimal places. Add your answer
