Classwork 2, Ch. 2 Problem 1: A Bugatti Chiron is one of the fastest cars in the word. In September 2017, the Bugatti Chiron accelerated from 0 to 249 mph and came back to rest in 42 second. Here is the video: https:[jyoutube/PkaleHUvQ The motion consisted of 4 parts: (i) At t = 0 sec, the car started at rest (at rest means a speed of 0 m/sec). From t = 0 sec to t = 5.12 sec, the car accelerated at 9.68 m/secz. (ii) From I = 5.12 sec to t = 13.32 sec, the car accelerated at 3.90 m/secz. (iii) From I = 13.32 sec to t = 33.24 sec, the car accelerated at 1.56 m/secz. (iv) From t = 33.24 sec to t = 41.80 sec, the car decelerated with an acceleration of 13.50 m/secz. At t = 41.80 sec, the car is at rest. What is the speed of the car at t = 5.12 sec? Hint: v = 170 + at. Give your answer in m/sec and mph. 1 m/sec = 2.237 mph. What is the speed of the car at t = 13.32 sec? Hint: v = 170 + at. Give your answer in m/sec and mph. 1 m/sec = 2.237 mph. What is the speed of the car at t = 33.24 sec? Hint: v = 170 + at. Give your answer in m/sec and mph. 1 m/sec = 2.237 mph. Sketch a velocity vs. time graph for the motion. Find the area under the curve of your velocity vs. time graph to find the total distance travelled by the car in meters and in miles in these 41.80 seconds. If you prefer, you can also use the kinematics equations to find the total distance travelled by the car in meters and in miles in these 41.80 seconds. Conversion Factors: 1 km = 1000 m and 1 mile = 1609.34 m. . . . 1 . . Hunt: The area of a triangle IS Atriangle = bh and the area of a trapezmd I5 2 1 Atrapezoid = 5(b1 + b2)h
