Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Hello Doctor, could it be a nice font with mentioning the name ((Murtada Ali Qassem) Thank you Doctor I will give you the admiration Q2/ PROBLEM 11.46 Car A is parked along the northbound lane of a highway, and car B is traveling in the southbound lane at a constant speed of 60 mi/h. At t= 0, A starts and accelerates at a constant rate a, while at t=5 s, B begins to slow down with a constant deceleration of magnitude a,16. Knowing that when the cars pass each other x = 294 ft and v = v, detemine (a) the acceleration a, (b) when the vehicles pass each other, (c) the distance d betwveen the vehicles at 1 = 0.

Car A is moving with constant speed v on the straight and level highway. The police officer in the stationary car P attempts to measure the speed v with radar. If the radar measures “line-of sight” velocity, what velocity v' will the officer observe? Evaluate your general expression for the values v = 74 mi/hr, L = 605 ft, and D = 19 ft, and draw any appropriate conclusions.

During the middle of a family picnic, Barry Allen received a message that his friends Bruce and Hal needed to be saved. Barry promised his wife Iris that he would be back in exactly 5 minutes. From that that picnic location, Barry runs at a speed of 600 m/s for 2 minutes at a heading of 35° north of west to save Bruce. He then changed his heading to 30° west of north, slows down to 400 m/s and runs for 1 minute to save Hal. (The changes in speed are essentially instantaneous and not part of solving this problem).(a) Draw a physical representation of the displacement during Barry’s full trip.(b) Use the Related Quantities sense-making technique to compare Barry’s total distance traveled to themagnitude of his displacement.(c) What average velocity (magnitude and direction) does Barry need to return back to the picnic inorder to keep his promise to Iris?
