3. Your engineering firm has been asked to determine the deceleration of a car during hard braking. To do so, you decide to measure the lengths of the skid marks when stopping from various initial speeds. Your data are as follows: TIH Skid length (m) Speed (m/s) 10 7 15 14 20 27 25 37 30 58 a. Do the data support an assertion that the deceleration is constant, independent of speed? Explain? b. Determine an experimental value for the car's deceleration- that is, the absolute value of the acceleration Your analysis method should involve fitting a straight line to an appropriate graph.

Potential Energy -- Kinetic Energy This graph shows different types of energy for a roller coaster car that starts at the top of a large hill and goes down to its lowest point at 6 s. According to the graph, what is the most likely relationship between height and potential energy? Your answer: They are directly related. They are inversely related. There is no relationship between the two. There is not enough information for a conclusion.

Assuming simple harmonic motion, determine the magnitudes of the velocity and acceleration of the bob after the pendulum has been in motion for 1.65 s. The magnitude of the velocity of the bob after the pendulum has been in motion for 1.65 s is 82699 ft/s. The magnitude of the acceleration of the bob after the pendulum has been in motion for 1.65 s is t/s2. Menu Tro Dicection In fuel

A snowboarder’s velocity is tracked by a pulse-laser velocimeter as she descends the slope. These velocity data are stored and analyzed via an embedded curve fitting procedure to determine a velocity function of v(t) = 1.5t2 + 2t + 2 (t is time in seconds and v is velocity in ft/s). At time equal 0, position (x) is zero. Find her position (e.g., distance traveled), velocity and acceleration formulations and values of each when time equals 15 seconds. Clearly write the formulas before finding respective values at t = 15 seconds!

You are the mechanical engineer supervising the layout of a piping system. In a certain portion of the pipe, the specifications are as follows: length of pipe is 10m, inside diameter of 30cm, outside diameter of 30.5cm, maximum allowable speed of 15m/s and a coefficient of 0.003456. If the uncertainties are 0.02mm for length, 0.8mm for the diameters and 0.1mm/s for the velocity, what loss of head will be imminent in this pipe? In the piping system above, what is the uncertainty in computed head loss contributed by the velocity of the pipe?
