A force of newtons accelerates an object from rest to m/s in seconds. What is the mass of the object (in kilograms)?

A 4.7 kilogram mass moving in a straight line at m/s is acted on by a force of newtons in the direction of its motion. Calculate the final speed of the object after seconds.

What force is required to change the speed of a 2.0 kilogram mass from m/s to m/s if it acts for seconds? The answer should be in newtons.
