After 1 second, the velocity is 4.5+1.5=6 m/s. After 3 seconds, the velocity is 4.5+3×1.5=9 m/s. After t seconds, the velocity is 4.5+1.5t m/s.
Explanation:
Δ v = u ln ( m i m ) . This result is called the rocket equation. It was originally derived by the Soviet physicist Konstantin Tsiolkovsky in 1897. It gives us the change of velocity that the rocket obtains from burning a mass of fuel that decreases the total rocket mass from m0 down to m.
