Question

An elephant weighing 40,000 N stands on one foot of area 1000 cm² whereas a girl weighing 400 N is standing on one ‘stiletto’ heel of area 1 cm².
Which of the two, elephant or girl, exerts a larger force on the ground and by how much?

Answer 1

Elephant has larger weight of 40,000 N, so elephant exerts larger force on the ground. Elephant exerts a large force on the ground by 40,000 N − 400 N= 39,600 N.
