Question 6 I can’t complete any of it as I don’t know which values to consider

Use the height (s) of the plane and the accelerated vertical motion of the bomb to find the time taken to fall to the ground.
For the vertical motion of the bomb, u=0
You know s and g so find t
When you know t, you consider the horizontal motion of the bomb, which is considered to be constant velocity with the value at which it left the plane.
These questions are all done the same way. Consider the horizontal and vertical motion separately. The vertical part is accelerated due to gravity, and the horizontal part is constant velocity. (The plane's velocity forward)
