Challenge Problems
Push your limits with challenges.
Question 1
A jet of water strikes a stationary plate at a velocity of 10 m/s with a cross-sectional area of 0.01 m² and density of 1000 kg/m³. Calculate the force acting on the plate due to the jet.
💡 Hint: Focus on applying the momentum change to find the force.
Question 2
During re-entry, a spacecraft expires propellants at a rate of 1 kg/s with an exit velocity of 2500 m/s. If the spacecraft's mass is 10000 kg and it was descending at 300 m/s, find the thrust and deceleration.
💡 Hint: Remember, thrust affects momentum and deceleration.
