A 700.0 N window washer is standing on a scaffold supported by ropes at each end. The scaffold weighs 200.0 N and is 3.00 m long. What is the force in each rope when the window washer stands 1.00 m from one end?

=force × distance a. work b. velocity c. pressure d. momentum

What properties of a moving object are used in determining the object's energy of motion

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
