Answer #1

using 2nd equation of motion along vertical

h = 0.5 gt^2

1180 = 4.9 t^2

t = 15.518 s

    A bomber plane is flying at a height “h” exactly level with the ground, and with a constant speed “v.” At time t = 0 the plane gently releases its payload (i.e. at the initial moment the payload is at rest with respect to the plane). Assume that after releasing the payload the plane continues to move with the same velocity as before. Answer the following questions based on this scenario. (You may use h = 490 meters and v...
