The 1.89-Mg dragster is traveling at 125 m/s when the engine is shut off and the parachute is released. (Figure 1) FD (kN) If the drag force of the parachute can be approximated by the graph, determine the speed of the dragster when it has traveled 400 m. Express your answer to three significant figures and include the appropriate units. με ? 50 20 20 400 s (m) v = Value Units Submit My Answers Give Up

Find the velocity (m/s) at which test should be run in a wind tunnel on a model wing of 11 cm chord in order that RN. shall be the same as for a wing with a 1.16 m chord at 41.4 m/s. Air under standard conditions in both cases. Round-off answer to the nearest hundredths.

1. 1) The acceleration of a particle moving along a straight line is a = (-C· /v) m/s², where C is a constant and vis velocity in m/s. If the constant Cis 1.5, and the initial velocity vo = 6.9 m/s at time t= 0, determine how far (in m) it has traveled when it stops. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.

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]

Required information An object like a bungee jumper can be projected upward at a specified velocity. If it is subject to linear drag, its altitude as a function of time can be computed as z = z0 + " (vo + ) (1 – e mg t where g= 9.81 m/s2, zo = 100 m, vo = 55 m/s, m= 80 kg, and c= 8 kg/s. Determine the time and magnitude of the peak elevation using the M-file. (Round the final answers to four decimal places.) The time of the peak elevation is The magnitude of the peak elevation is m.

Refer to the picture below.
