If an object accelerates from rest, with a constant acceleration of 5.4 m/s2, what will its velocity be after 28s?

A 25.0-N force is applied to a 5.0-kg object to accelerate is rightwards. The object encounters 15.0-N of friction. Determine the acceleration of the object. (Neglect air resistance.) show your work below.

A car accelerates uniformly from 0 to 15m/s in 5 s. Calculate acceleration.
