Alpha Centauri is 4.4 lightyears away. Traveling at 1/10 speed of light it would take you 44 years.
The force is being pulled my the gravity or it could be a third party thing like a black hole you feel me
0 N. It's being pushed up the same amount it's being pushed down, so it cancels out.
Answer:
Range will become 4 times of initial range
Explanation:
Let the velocity of projection is u
And angle at which projectile is projected is 
And acceleration due to gravity is 
So range of projectile is equal to
........eqn 1
Now in second case it is given that velocity of launching is doubled
So new velocity 
So new range will be equal to
.....eqn 2
Now dividing eqn 2 by eqn 1


So if we double the initial launch speed then range will become 4 times
