SUMMARY
The maximum height of a rocket with a body mass of 0.49 kg and 1.47 kg of fuel, consuming fuel at a rate of 0.49 kg/s with an exhaust speed of 60 m/s, can be determined through thrust calculations and kinematic equations. The thrust produced by the rocket engine is calculated using the formula F = ṁ * v_e, where ṁ is the mass flow rate and v_e is the exhaust speed. After the fuel is exhausted, the rocket behaves as a projectile, allowing for the calculation of maximum height using kinematic equations.
