A 2.65 kg mass oscillates back and forth on a spring with a velocity vector that varies as a function of time according to the following v(t)=(3.95cm/s) sin [0.79 rad/s]
What is the maximum speed of mass?
What is the spring constant if the spring in n:m?
How fast us the mass moving at t= 5.0 sec in m/s?
Description of Physics - Mechanics - Force, A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 200 N and is 3.00 m
An observer inside the building notices that it takes 0.15s for the tile to pass her window, whose height is 2.20m. How far above the top of this window is the roof.
