A Physics Question. A Plane dropped from an aircraft flying horizontally at 40 m/s a bomb.?

Presumably you neglect air resistance.

1) The horizontal distance travelled at time t s is 40t, at a constant 40 m/s

2) The vertical distance travelled is - 1/2 g t^2 m, and the vertical component of velocity is -gt m/s

3) When the plane hits the ground, - 1/2 g t^2 = - 100 m

BEFORE GOING ANY FURTHER, make sure you understand why all these statements are true.

You can now use (3) to find t at impact, and use (1) and that particular value of t to find horizontal distance travelled before impact

You can use (2), second part, to find vertical component of velocity. Horizontal component of velocity is, as always, 40 m/s. Show these on a diagram and you can finish the problem. (Hint: you can use Pythagoras for (c) )

a...where's the initial drop .....don't understand b......c... i believe from a certain height all things reach terminal velocity without some sort of thrust...d would that not depend on the weight factor of the front and back of the device
