Question

4. A desk with a mass of 10 kg is pushed across a floor with an acceleration of 4 m/s?. What
is the force on the desk? Use the equation F = ma.

Answer 1

40 N. If you’re using F=MA MxA would be 10x4 which would get you 40 N

Answer 2

Answer:

Below

Explanation:

All we need to do for this question is to plug in our values and solve!

      Force = mass x acceleration

      Force = 10 kg x 4 m/s^2

     Force = 40 Newtons or 40 N

If your teacher requires you to round to sig figs it would be :

    F = 4 x 10^1 N

Hope this helps!
