Challenge Problems
Push your limits with advanced challenges
A truck collides with a stationary car. If the truck's mass is 2000 kg and its speed is 10 m/s, find the total momentum before and after the collision if the car's mass is 1000 kg and it moves at 5 m/s after the collision.
💡 Hint: Use conservation of momentum where initial equals final.
Consider a fluid flowing into a control volume. If the fluid has a density of 1000 kg/m³ and flows at 2 m/s in a pipe with a cross-section of 0.5 m². Calculate the mass flow rate entering the control volume.
💡 Hint: Recall the formula for flow rate to find the answer.
