0 m/s, the ball will stop before transferring to the force of gravity on earth (-9.8 m/s^2) starts acting on it.
Explanation:
9420 km/hr is the correct answer
Hope this helps...☺
Answer:
Explanation:
Let fuel is released at the rate of dm / dt where m is mass of the fuel
thrust created on rocket
= d ( mv ) / dt
= v dm / dt
this is equal to force created on the rocket
= 220 dv / dt
so applying newton's law
v dm / dt = 220 dv / dt
v dm = 220 dv
dv / v = dm / 220
integrating on both sides
∫ dv / v = ∫ dm / 220
lnv = ( m₂ - m₁ ) / 220
ln4000 - ln 2500 = ( m₂ - m₁ ) / 220
( m₂ - m₁ ) = 220 x ( ln4000 - ln 2500 )
( m₂ - m₁ ) = 220 x ( 8.29 - 7.82 )
= 103.4 kg .
1 AU ~150,000,000 km/160 km/h, which gives you hours.
24 hours in a day...

If you are planning on a return trip plan on your 5 to 6x great grandchildren picking you up at the space port.
Answer: (2) > (1) > (3) > (4)
Explanation:
(1) a +1 charge and a -1 charge separated by 200 pm:
The potential energy in this case will be,
(2) a +1 charge and a +1 charge separated by 100 pm:
The potential energy in this case will be,
(3) a +1 charge and a -1 charge separated by 100 pm:
The potential energy in this case will be,
(4) a +2 charge and a -1 charge separated by 100 pm:
The potential energy in this case will be,
So, the order from <u>highest</u> potential energy <u>to lowest</u> potential energy is:
(2) > (1) > (3) > (4)
