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.
Two identical clocks are synchronized. One is then put in orbit directed eastward around the Earth while the other remains on the Earth. Which clock runs slower? When the moving clock returns to the Earth, are the two still synchronized?
