◦•●◉✿Weight is mass (in kg) x 9.8, which gives 0.050 x 9.8 = 0.49 N. The resultant force is the thrust – weight = 5 – 0.49 = 4.51 N (unrounded). Acceleration = resultant force divided by mass = 4.51 ÷ 0.050 = 90 metres per second squared (90 m/s2). This means that, every second, the speed of the rocket increases by 90 m/s.✿◉●•◦

PHYSICS

For a Rocket propulsion velocity of exhaust gases relative to rocket is 2 km/s. If mass of rocket system is 1000 kg, then the rate of fuel consumption for a rocket to rise up with an acceleration 4.9 m/s

ANSWER

Relative velocity of exhaust gas V=2 km/s=2000 m/s

Thrust force F
