In: Physics
A horizontal force with a magnitude of 30 N pushes a block which
has a mass of 4.19 kg on the floor which has a coefficient of
kinetic friction of 0.51.
How many Joules of work does the force do to the floor-beam system
as the block travels 3.86 m along the floor?
During movement on the floor, the heat energy in the block
increases by 39.5 J. What is the Joule of increase in heat energy
in the floor?
How many Joules is the increase in the kinetic energy of the block
during the move?
Here work done by the force will be utilised in increasing kinetic energy of the Block and energy loss agaifriction work done.
here the Energy Lost in friction will result in heating the floor as well as the block. So we can say That, Heat energy developed in the floor + Heat energy developed in the block= - Work done by friction.
