how much ( in newtons) does a 0.5 kg of salami weigh?

Answer 1

F = mg
F = 0.5 x 9.8
F = 4.9 Newtons

Answer 2

This is weight you are talking about.

so it will use the equation F=mg

where m is th mass of the object
g is the acceleration due to gravity, which is conventionally known to be 9.8 ms/s

therefore, the answer would be 0.5 * 9.8
=4.9N

and of course as force is vector quantity, hence there must be a direction involved. assuming the salami is on a flat table, the direction would be down.

this is merely a general answer, as in the question it is not specified whether the weight you seek is apparent or actual.

Answer 3

You realize that it works even if this is not salami?

The relationship between mas and force is acceleration, and acceleration due to gravity on the surface of the earth is 9.81 m/s^2.
So half a kilogramme would weight 4.905 newton.

Answer 4

You sometime simplify g=9.8 to with 10.

g is Netwon per kilo

so o.5 kg = 5 N

Answer 5

I'm assuming you mean here, on earth.

F = mg

F = .5 x 9.8

F = 4.9 N

Answer 6

a = 9.81m/s^2

so weight = (9.81)(0.5) = 4.905N
