Arocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 56.6 × 105 kg, of which 8.50 × 105 kg is fuel. the rocket engine is then fired for 240 s, during which fuel is consumed at the rate of 350 kg/s. the speed of the exhaust products relative to the rocket is 2.38 km/s.
(a) what is the rocket's thrust? after the 240 s firing, what are
(b) the mass and
(c) the speed of the rocket?

b) 5546000 kg

c) 48.42 m/s

Explanation:

Mass of fuel = 8.5×10⁵ kg

= Mass of ship = 56.6×10⁵ kg

R = Burn rate = 350 kg/s

= Speed of the exhaust products relative to the rocket = 2.37 km/s

Thrust

Thrust is 833000 N

Mass of fuel consumed in 240 s

350×240 = 84000 kg

Mass of ship after 240 s

Mass of ship after 240 s is 5576000 kg

Speed of rocket

The speed of the rocket after 240 s is 35.58 m/s

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

statement #3 on andre"s list is false.
