to use a machine,u must do the work on the machine called input work. the machine then foes the work on and object called output work. not all the input work gets transmitted to output work. some work is lost due to friction in the machine. if a machine has an input work of 250 joules and 25% of the input work is lost due to friction, what is the output work of the machine.

    25% of 250 joules is lost to friction.
    so 75% of 250 joules must be the output (assuming no other loses).
