Answer:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

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/ $s^{2}$ .
