A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
emmainna [20.7K]

Answer:

The deceleration of the plane is 0.25 m/s^{2}.

Explanation:

Deceleration is the converse of acceleration.

From first law of motion, we have;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Thus,

v = 50 m/s

u = 80 m/s

t = 120 s

50 = 80 + 120a

50 - 80 = 120a

-30 = 120a

a = \frac{-30}{120}

  = -0.25

a = -0.25 m/s^{2}

The deceleration of the plane is 0.25 m/s^{2}.

8. The diagram below shows the shift in the spectrum for hydrogen light from several different sources in the universe.
igor_vitrenko [27]

Answer:

more distant galaxies are moving away faster.

the shift towards red (Doppler effect like with sound on Earth) is the indication.

Explanation:

what did this have to do with biology ?

and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...
