Question #d734d

Answer 1

`43.75 N`

Explanation:

Using Newton's equation for force:

`F = m * a`
`F = (12.5 kg) * (3.5 m/s^2)`
`F = 43.75 kg * m/s^2` or `43.75 N`

Answer 2

I tried this:

Explanation:

Here you can use Newton's Second Law that tells us that the resultant of all the forces acting on a body of mass `m` will produce an acceleration `a` or:
`SigmavecF=mveca`

in your case you can assume a movement in one dimension and lose the vector notation to write (havinhg one force only):
`F=ma`

you only need to substitute your given values for mass and acceleration and multiply to get your force in Newtons.
