An object with a mass of 10 kg is moving along a horizontal surface. At a certain point it has 40 J of kinetic energy. If the coefficient of friction between the object and the surface is 0.60, how far will the object go beyond that point before coming to a stop

no simpler subs form complex ones. synthesise = make

the answer is b, have negligible mass

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the awnser is d you right bro
