Homework Statement


A very strong 100kg man is having a tug of war with a 1500 kg elephant. The coefficient of static friction for both on the ground is 1.0.
a) Find the force needed to move the elephant.
b) What would happen if the man could actually exert such a force?

Homework Equations


Ff = μs * Fn
FN = mg

The Attempt at a Solution


a) Using the above equations, I got the total frictional force, and thus the applied force to be 14,700 N. Is this correct?
b) The man would slip and fall. <----- Is that what they're looking for?

looks good! :smile:

he would slip, but why would he fall?

hint: what would happen on ice? :wink:
