Challenge Problems
Push your limits with advanced challenges
A rocket with a mass of 100 kg starts in space at rest. If it expels gas at a velocity of 50 m/s, what will be the rocket's velocity if it ejects 10 kg of gas?
💡 Hint: Apply the conservation principle and carefully set the equations.
Consider a 2 kg object traveling at 5 m/s collides elastically with a stationary object of mass 3 kg. What are the final velocities of both objects?
💡 Hint: You will create two equations to solve for the unknown velocities after collision.
