I saw this question answered somewhere else but they didn t convert kg to N, don t you have to do that?
Barker is unloading 20 kg bottles of water from his delivery truck when one of the bottles tops over and slides down the truck ramp that is inclined at an angle of 30 degrees to the ground. what amount of force moves the bottle down the ramp?
I mean converting kg to newtons before even doing the problem
F = m*g*sinΘ = 20*9.8*sin30° = 98 N
If the question asks for force, it MUST be Newtons, as kg is a mass, not force.
