Physics
You must know the acceleration.
Physics
You can not.
Dynamics, Math
The horizontal velocity of plane and bomb do not change, so the bomb hits right under the plane. Hint: Turn your plane after releasing the bomb.
Dynamics, Math
The bomb lands right under the plane.

total vertical fall of ball = .591 + .048 or .639 meters loss of potential energy by ball = .0961 * 9.81 * .639 = .602 Joules so (1/2) k (.04754)^2 = .602

well, you know l = w because the base is square. v = w^2 h = 300 mL = .3 *10^-3 m^3 so h = 3 * 10^-4 /w^2 cardboard area bottom and top = 2 w^2 sides = 4 w h so A = 2 w^2 + 4 w h A = 2 w^2 + 4 w (3*10^-4)/w^2 A = 2 w^2 + 12*10^-4 /w dA/dw = 4 w -1.2*10^-3/w^2 = 0 fo min 4 w^3 ...
math
30, 60, 90 triangle 1, sqrt 3, 2 sin 30 = 1/2 cos 30 = sqrt 3/2 cos is negative in quad 2 and quad 3 so 180 - 30 = 150 degrees 180 + 30 = 210 degrees
math
a + b = 680 a/b = 2/3 2 b = 3 a a = (2/3) b so (2/3) b + b = 680 (5/3 ) b = 680 b = 408 then a = (2/3)408 = 272 then b - a = 136 ml
