If a 50 N force pulls on a 10 kg object, how much acceleration will occur?

Assuming that the force of friction does not equal to the force at which you are pulling at, hence Fnet is not zero, to solve for acceleration need to use the following equation:

Fnet = ma

a = Fnet/m

a = 50 N/10 kg

a = 5 N/kg or a = 5 m/s^2.
