This problem set deals with the problem of non-constant acceleration. Two researchers from Fly By Night Industries conduct an experiment with a sports car on a test track. While one is driving the car, the other will look at the speedometer and record the speed of the car at one- second intervals. Now, these aren't official researchers and this isn't an official test track, so the speeds are in miles per hour using an analog speedometer. The data set they create is: {(1,5), (2, z), (3, 30), (4, 50), (5, 65), (6,70)} Z=25 They notice that the acceleration is not a constant value. They decide that a fourth-degree polynomial will be the best to describe the speed of the car as a function of time. The task here is to determine the fourth-degree polynomial that fits this data set the best. Exercises 1. Use a general fourth-degree polynomial and Fly By Night's data to construct six equations. Note that the equations are linear in the coefficients. Write the equations here: 2. Construct the least-squares problem Ax = b. A = 3. Construct the system of normal equations AT Ax = A¹b. ATA = b = ATB =

2. Connor lives on a steep hill and wants to conduct a Dynamics experiment with his car. He starts from rest at the top of the hill and releases the brakes. His acceleration down the grade is a function of velocity and is described by the equation a = 3.22 0.04v² where v is the velocity of his car in ft/sec. Predict the velocity of Connor's car at the bottom of the grade in mph. [Ans. to check: 6.12 mph] A 600¹ V

The wheel starts rotating from rest, 2) if its angular velocity Was a function of angular position 0 is W=0.1-0², where O is in radian, and its radius ris 0.2 m, what is the magnitude of the angular acceleration (in rad/s?) of the wheel after the wheel has turned 1.1 revolution(s) from rest. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. P
Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C. When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew? Q2. Your car tire pressure sensor looks to see when your tire pressure…
The graph to the right shows velocity vs. time for a cart on a track with a friction pad attached. The cart was launched from rest by a hoop spring. Use this graph to answer the following question: so long as the ramp is level, even with the friction pad NOT in contact with the track it is impossible to produce a region "b" that is flat (horizontal), i.e. that shows a constant velocity. This is because b V a of errors inherent to the motion detector the acceler tion gravity causes the cart to rate air currents in the room significantly affect the motion of the cart there is still a small amount of friction between the wheels of the cart and the track, and the axels of the cart with the body of the cart achieving constant velocity is not physically realistic under any circumstances

Two small objects of mass mo and a rotating platform of radius R and rotational inertia I, about its center compose a single system. Students use the system to conduct two experiments. The objects are assumed to be point masses. Experiment 1 mo R mo Fo Figure 1 Each object of mass mo is placed a distance rị away from the center of the platform such that both masses are on opposite sides of the platform. A constant tangential force Fo is applied to the edge of the platform for a time Ato, as shown in Figure 1. The system is initially at rest. Experiment 2 R r2 r2 Fo Figure 2 Each object of mass mo is placed a distance r2 away from the center of the platform such that both masses are on opposite sides of the platform. Distance r2 < rị .A constant tangential force Fo is applied to the edge of the platform for a time Ato , as shown in Figure 2. The system is initially at rest.
