An object has a mass of 5 kg. what force is needed to accelerate it at 6 m/s2? (formula: f=ma)

Explanation:

According to Newton's second law, a force applied to certain object will accelerate it, that's the meaning of the formula:

So, in this case, we don't have to analyse much, because all values are given, we just have to replace them and solve for F:

Therefore, the force needed to accelerate that mass is 30 N.
