Lawn Mower To mow the yard, Shaima pushes a lawn mower 1.2 km with a horizontal force of 66.0 N.
Does all of the applied force do work on the mower,
and how much work does Shaima do on the mower?

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
