Question

A rocket of initial mass 6000 kg ejects gases at a constant rate of 16 kg/s with a constant relative speed of 11 km/s. What is the acceleration of the rocket one minute after the blast?

Hint:

The acceleration of a rocket can be calculated using the formula \( a = \frac{\dot{m} \cdot v_r}{m} \), where \( \dot{m} \) is the rate of mass ejection, \( v_r \) is the relative speed of ejected gases, and \( m \) is the remaining mass.
