A stealth bomber is flying straight and level at a constant speed of 150 m/s at an altitude of 3500 m above the ground. It drops
dangina [55]
Height = \frac{1}{2} gt^2 \\ \\ 3500 = \frac{1}{2} (9.8)(t^2)\\ \\3500 = 4.9t^2\\\\t^2 =714.285714286\\\\\boxed {t=26.73~seconds}



\sf Horizontal ~distance = velocity \times time\\\\ Horizontal distance =150 \times 26.73 \\\\Horizontal ~distance =4009.5

Answer:

a = (v2 - v1) / t

From A to B    (8 - 4) m/s / 1 s = 4 m / s^2

From A to D    ( 7 - 4) m/s / 5 s = .6 m / s^2

Note these equations hold for "uniform" values

They say nothing about the acceleration at intermediate points - the equation just says that his average speed increased from 4 m/s to 7 m/s during a 5 sec period
