A 2000 kg truck is moving at 20 m/s. It encounters a sudden obstacle causing a change in momentum due to an emergency stop. Calculate the required stopping force if it takes 5 seconds to stop.
💡 Hint: Remember that force relates to the rate of change of momentum.
A water tank has two exits with different velocities, flowing out. How would you calculate the net force acting on the tank due to these exits?
💡 Hint: Consider that pressure at the exits might affect your calculations.
