Q6 The relationship between the velocity, u, of a construction vehicle (in km/h) and the distance, d (in metre), required to bring it to a complete stop is known to be of the form d = au² + bu + c, where a, b, and c are constants. Use the following data to determine the values of a, b, and c when: a) u 20 and d = 40 b) u = 55, and d = 206.25 c) u = 65 and d = 276.25 [Note: Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software]
9. A spring has a stiffness of 100N/m. A mass of 3 kg was attached to the spring. The mass was pushed 10cm upward from the equilibrium position and was released from rest. After 5 seconds from release, determine the acceleration of the mass in m/s^2? 10.What Law governs the statement, "For every object applied with a load, the displacement or size of deformation is directly proportional to the magnitude of the applied load"?
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!

1) Is it possible to prescribe the velocity v0, so that the pendulum keeps rotating with alpha = pi/2 Explain clearly why? Given: L, g, and m. 2) After transient motion, the pendulum settles at steady state rotation atalpha = pi/3. Find the initial velocity v0. Given: L, g, m, sin(pi/3) = (squareroot(3)/2), cos(pi/3) = (1/2). [Hint: Use the conservation of energy and the 2nd Newton’s law.]

Applying principles of dynamics A usual football tryout involves a player running a 40-yard dash. If a particular player finishes the dash in 4.25 seconds while reaching his maximum speed at the first 16 yard mark with a constant acceleration and then maintains that speed for the remainder of the run, determine this person’s acceleration over the first 16 yard, his maximum speed and how long he accelerated.
