Final answer:
The force experienced by a wall when water strikes it normally at a speed of 10 m/s and discharge 0.0001 m^3/s is 1 Newton, calculated based on the conservation of momentum.
Step-by-step explanation:
The force experienced by a wall when water strikes it normally can be determined using the principles of conservation of momentum and Newton's laws of motion. Considering that the water flow stops upon impact, the change in momentum per second is equal to the mass flow rate times the velocity of the water just before impact.
In this case, the discharge rate is 0.0001 m3 s-1 and the density of water is typically 1000 kg m-3. Multiplying the discharge rate with the density gives us the mass flow rate, which is 0.1 kg/s. Using the velocity of 10 m/s, the change in momentum per second (force) is calculated as:
Force = mass flow rate × velocity = 0.1 kg/s × 10 m/s = 1 N.
Hence, the force experienced by the wall is 1 Newton.
