A block with mass m = 16.0 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 5205.0 N/m after being compressed a distance x1 = 0.481 m from the spring's unstretched length. The floor is frictionless except for a rough patch a distance d = 2.9 m long. For this rough path, the coefficient of friction is ?k = 0.4.
How much work is done by friction as the block crosses the rough spot?
What is the speed of the block after it passes the rough spot?
Instead, the spring is only compressed a distance x2 = 0.111 m before being released.
How far into the rough path does the block slide before coming to rest
What distance does the spring need to be compressed so that the block will just barely make it past the rough patch when released?
A heat engine has an efficiency of 61.5% and it exhausts 7500 J of waste heat into the environment. How much work is performed by the previous heat engine
An ore car of mass 4 000kg rolls downhill on tracks from a mine. At the end of the tracks, 10 m lower in elevation, is a spring with k = 400 000 N/m. How much is spring compressed in stopping the ore car? Ignore friction.
