we have a test coming up and I cannot figure out the practice question. Can somebody please help?

Aaron throws a 7.5 kg bowling ball by applying a 45 N force for a time of 0.90seconds. What is the impulse Aaron applies to the ball?
What is the ball's speed at the end of this action?

Thank you for all your help.

Impulse=force*time=mass*changevelocity

I assume you can d o that.
