Calculate the pressure exerted on the floor when an elephant who weighs 24,000 N stands on one foot which has an area of 0.4 m. 3. Calculate the pressure exerted on the heel of a boy's foot if the boy weighs 320 N and he stands on one heel which has an area of 0.16 m. 4. How much must a woman weigh if she exerts 800 Pa pressure while standing on one foot (which has an area of 0.6 m-)? 5. What is the area of a car that touches the road if the car's weight on that tire is 30.72 N and the pressure exerted on the road is 48 Pa? 6. Calculate the pressure exerted on an elevator floor which has an area of 6 m, if 20 people whose combined weight is 15,000 N are standing on it. (Assume their weight is spread evenly across the floor.) 7. How much pressure is exerted on a science lab floor if the lab desk has an area of 1.08 m and a force of 12,000. N 8.
