Newton`s Second Law
... A 10 kg object is subject to a net force of 25 N. What is the acceleration of the object in m/s2? The second law says a = F/m. Therefore a = 25 N /10 kg = 2.5 m/s2 If the object starts at rest, then how long will it be before its velocity is 25 m/s? You know that v = v0 + at and v0= 0. Rearranging g ...
