How to define a constant velocity of second order system in a limited time in Simulink

Hi all,

I want to simulate a model (Mass, Spring and Damper) which is considered a second order system.

A Mass was applied a constant velocity in a limited time (=1s). After that, a constant velocity was turned off.

How to define a constant velocity of second order system in a limited time in Simulink?

Could you have any suggestions?

Did you try using a signal generator to create the velocity signal?

Not, yet.

How to create the velocity signal (a constant velocity) from a constant velocity?
