Consider a piston engine airplane with a parasite drag coefficient of 0.02 when its landing gear is retracted, and 0.025 when it is deployed. assume that the other drag polar parameter k does not change. the airplane is deigned to cruise for minimum power requirement with its landing gear retracted at certain altitude. determine the % increase or decrease in the minimum power required if the airplane executes the same flight with its landing gear deployed (as may happen if its retraction mechanism fails)

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 โ t2)k (iv) r (t) = 2t j + (50 โ t2)k (v) r (t) = (50 โ 2t) i + 2t j + (50 โ t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
