A hippo has a mass of 6000kg. When standing on 4 feet, how much pressure is exerted on the ground? Assume each foot has an area of 0.10 square meter. Show your work.

will do Ms. Sue but can you help me answer the questions
To calculate the pressure exerted by the hippo on the ground, we need to use the formula:
Pressure = Force / Area.
First, we need to calculate the force applied by the hippo. Force can be calculated using the formula:
Force = mass × acceleration.
In this case, the mass of the hippo is given as 6000 kg. Since it is standing still, we can assume the acceleration is 0. Therefore, the force applied by the hippo is:
Force = 6000 kg × 0 m/s^2 = 0 N.
Now that we have the force applied by the hippo, we can calculate the pressure it exerts on the ground.
Since the hippo stands on four feet, we need to consider the total area they cover. The area covered by each foot is given as 0.10 square meters. Therefore, the total area covered by all four feet is:
Total Area = 4 feet × 0.10 square meters/foot = 0.40 square meters.
Finally, we can calculate the pressure exerted on the ground using the formula:
Pressure = Force / Area.
In this case, the force is 0 N, as we previously calculated, and the total area is 0.40 square meters. Therefore, the pressure exerted by the hippo on the ground is:
Pressure = 0 N / 0.40 square meters = 0 N/m^2.
Therefore, when standing on all four feet, the hippo exerts no pressure on the ground.
