A 40 kg tight rope walker is 50 m up in the air as they cross over a street between a couple of buildings. As they take a step they apply 45 N of force on the rope.
The rope at that time applies
N of force on the tight rope walker.

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
