How long does it take to go 32 meters at 47 m/s?
32 = 47 t
t = 32/47
32 = 47 t
t = 32/47
1. Calculate the relative velocity (v_rel) of the arriving plane with respect to the stationary plane. Since the arriving plane is landing and passing the stationary plane, the relative velocity is the sum of the landing speed (v_landing) of the arriving plane and the speed of the stationary plane (which is zero).
v_rel = v_landing + 0
v_rel = 47 m/s + 0
v_rel = 47 m/s
2. Calculate the time (t) the moving plane is visible by dividing the length of the moving plane (L_arriving) by the relative velocity.
t = L_arriving / v_rel
t = 32 m / 47 m/s
t = 0.68 seconds (approximately)
Therefore, the moving plane will be visible to the passenger for approximately 0.68 seconds.
