Problem 9.19 Part A A mass $m_A = 1.4$ kg, moving with velocity $\vec{v}_A = (3.8\hat{i} + 4.0\hat{j} - 2.0\hat{k})$ m/s, collides with mass $m_B = 3.8$ kg , which is initially at rest. Immediately after the collision, mass $m_A =$ 1.4 kg is observed traveling at velocity $\vec{v'}_A = (-2.0\hat{i} + 3.6\hat{k})$ m/s. Find the velocity of mass $m_B$ after the collision. Assume no outside force acts on the two masses during the collision. Enter the x, y, and z components of the velocity separated by commas. Express your answer to two significant figures. $v_{Bx}, v_{By}, v_{Bz} =$ m/s

Problem 4 (20') The lift and drag coefficients for a rectangular wing with a 10 m chord (L) at takeoff are 1.0 and 0.05, respectively. Density of air is 1.225 kg/m$^3$. Find: (1) Span S needed to lift the weight of 3560 kN at a take-off speed of 282 km/h. Planform area $A_p$ = Chord \times Span = L \times S. (10') (2) Drag force at this condition. (10')

(a) Let a > 0 be fixed. Given $f'(x) = f(x-a)/a$, and if $f(x) = (x/a)^{1/2}$ for $0 \le x \le a$ prove that $f(x) = 1 + \frac{2}{3} \left(\frac{x}{a} - 1\right)^{3/2}$ for $a \le x \le 2a$ assuming continuity at $x = a$.
