Voyager is about 141 au from earth. what is voyager’s distance from earth in light years?

1 AU = it is defined as distance of Earth from Sun

it is also known as solar distance

So here we know that distance of Earth and Sun is

1 Light Year = It is defined as the distance covered by light in 1 year of time

it is calculated by simple product of speed * time

= speed of light

now we can find the value of 1 Ly

now Voyager distance is given as

now in order to convert it into Ly we can say

now we have

so the distance in light year must be 0.00224 Light years

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
