Hermes Simmons pulls a box along a frictionless surface with a rope that makes a 60 degree angle relative to the ground. The tension in the rope is 10 N, the box moves total horizontal distance of 4 m, and it takes him 2 seconds to this. What's Hermes' power output in Watts?

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
