A force of 1.2N is applied to an object of mass 1.5Kg. It accelerates at 0.50 m/s^2. Determine the Force of friction and the Coefficient of Friction(adsbygoogle = window.adsbygoogle || []).push({});

This is what I did. However, it seems that the Force of Friction is really low so I'm not sure if I did this question right.

F=M * A ..which is can also be used as Fnet

.:. Fnet= 1.5kg(0.50 m/s^2)

= 0.75 N

Fapp= 1.2 N

Fnet=Fapplied + Ffriction

Ffriction = Fnet-Fapplied

= 0.75n -1.2 n

= - 0.45 N

If I continue to Figure out the coefficient of Friction it seems very unreasonable.

Ffriction/ Fnormal = kinetic Coefficient

-.45n/ -9.8m/s^2 * 1.5kg

= .0382

This may be right but I'm not quite sure. Any input would be great.
