Challenge Problems
Push your limits with challenges.
Question 1
A horizontal jet of water strikes a vertical plate at 5m/s with an area of 0.05 m². Calculate the force required to keep the plate stationary if the water has a density of 1000 kg/m³.
💡 Hint: Use the density and velocity to find the momentum.
Question 2
If a spacecraft is decelerating using a jet that discharges at 100 kg/s with a jet velocity of 1500 m/s, calculate the thrust generated given the original speed was 600 m/s.
💡 Hint: Use the formula for thrust based on mass flow rate and jet speed.
