Question

a box of mass 45kg off a cliff.  whatis the weight of the box

anonymous · Answer

$$weight=mass*acceleration, acceleration=gravity=9.8\frac{ m }{ s ^{2} }$$
We have weight and acceleration. And just substitute in the equation
$$w=mg$$
$$w=(9.8\frac{ m }{ s ^{2} })(45kg)=441 N$$, N=$$\frac{ kg*m }{ s ^{2} }$$

Just as Charlie stated, weight=ma The acceleration here on earth is 9.8. Because N(newtons-unit for force) is in (kg)(m)/s, you don't need to do any conversion. Just multiply 9.8 by 45 to get your answer in Newtons. You should end up with 441! If you add direction to make it a vector quantity, you just add the word down. Simple right? Well I hope this helped clarify what Charlie was pointing out! Good Luck! If you ever need any other clarification, feel free to message me! :)
