Displacement, Velocity, and Acceleration

Abstract
In this report I will answer the questions that were given as the assignment for the case project.

|1. Alamogordo and Cloudcroft (both towns in New Mexico) are 19.5 miles apart via US Hwy 82, a steeply uphill, twisting mountain|
|road. An 18-wheeler makes the trip in 45 minutes. (A) What is the truck's average speed? Assume the truck's speed is |
|constant, since it's crawling all the way in second gear (a safe assumption). (B) Is the truck's velocity also constant? Why |
|or why not? |
|(A) Distance Traveled / Time of Travel = average speed |
|19.5 miles / 45 minutes = 0.43 mi/min (Trucks Average Speed) |
|(B) No, the trucks velocity is not constant because it is traveling on a twisting mountain road; because the path is not |
|constant the velocity will not stay constant. |
|2. The M61 "Vulcan" cannon is a Gatling Gun-type weapon deployed on aircraft. It fires a 100g, 20mm diameter projectile at a |
|rate of up to 6,000 shots per minute. Barrel length is 170 cm, and muzzle velocity (speed of the projectile leaving the barrel)|
|is 1030 m/s. |
| a. Assuming constant acceleration, what is the mean (average) velocity of the projectile in the barrel?...
