Question

a rocket of initial mass 6000 kg object mass at constant rate of 1 kg per second with constant relative speed of 10 M per second the acceleration of the rocket after 5 seconds is

Answer 1

After 5 seconds, the mass of the rocket is

M₂ = 6000 - 1(5) = 5995 kg

M₁ = 6000 kg.   dm/dt = 1 kg/s

F = dP / dt

F = v (dm/dt)

M₂a = v (dm/dt)

5995a = 10 (1)

a = 0.00166 m/s²
