Question

Frick and Frack are standing back-to-back, leaning on each other, but not moving. If Frick weighs

165 pounds and Frack weighs 210, who is pushing harder?

Answer 1

Frick is pushing harder

Step-by-step explanation:

if Frack weighs more and he was pushing harder they would be moving, but if Frick pushes harder then they wont move

Answer 2

they are both pushing with the SAME force

Step-by-step explanation:

Since no one is moving, the system of the two friends is NOT accelerated, which means that the net force on it is zero. then, the force applied by each is of the SAME magnitude but in opposite directions.

Therefore they are both pushing with the SAME force.
