Solve the all parts of given question:

Question: The displacement of a 1kg object as a function of time t in the x-y plane is given by x=20t+30t² and y=25-30t, where x and y are in units of meters and t is in seconds.

Part I: The force acting on the object is?

Part II: The magnitude and direction of the velocity of the object from the positive x axis at the end of 1 second would be?

It'd be really helpful if you could show all steps of your work. Thanks.
