Frictionless Situations - How to get Velocity -Time information

[Sonny18n]

Need help understanding this: http://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Force/Force-Exercise-1

This comes with it: http://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Force/Force-Interactive

For my first trial I placed the values as instructed and got a net force off 10 and an acceleration of 5m/s^2.
How do I get the Velocity-Time information?

how did you get the acceleration?

how did you get the acceleration?

On the graph the first point shows you.
