There are multiple ways, including feeding in the Simulation time as a signal and using a Math block or two in order to calculate 1/2 * t^2

Thank you for your answer. In your reply, you have done the integration in mind . But i want the integration to be done by the matlab itself, is there any specific way if suppose i dont know integrating t is half of t square.

This is 0.5 * t^2 + C with C is a constant expression depending e.g. on the initial value of t. For t(0)=0, C is 0 also.
Do you need the solution only, or is it a homework question to solve this in Simulink? If so, please mention this explicitly.
