Amachine with a mechanical advantage of 2.5 requires an input force of 120 newtons. what output force is produced by this machine?

Mechanical advantage (ma) = output force/input force 
output force = ma×input force = 2.5×120 = 300 n

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
