A truck experiencing drag is able to reach a maximum velocity of v1 = 49.1 m/s. It has cross- sectional area A1 = 1.8 m^2 and coefficient of drag CD,1 = 0.54. The city is having a parade and you want to use your truck as a float. After fitting your truck with signs and posters, the new cross- sectional area is A2 = 3.1 m^2, and the coefficient of drag has increased to CD.2 = 1.04. What is the new maximum speed of your truck? Give your answer to 1 decimal place. Assume the density of air is 1.204 kg/m^3 and does not change, and assume the accelerating force provided by the engine does not change.Two massless springs with different spring constants k1= 99 N/m and k2 = 6 N/m are aligned vertically, as shown in figure 1. A block of mass m = 0.07 kg is placed on the bottom spring. The distance between the top of the box and the top spring is h = 0.38 m. You compress the bottom spring Ay = 0.20 m from its equilibrium position (figure 2). When you let go, the box flies up (figure 3) and compresses the top spring (figure 4). Treat the upward direction (1) as positive, such that the compression of the top spring is a positive displacement. What is the maximum compression of the top spring due to the flying box? Give your answer in units of meters to 2 decimal places. Use g = 9.8 m/s^2. Assume air resistance is negligible. 2 w 4 M M Ay M
