Compute all parts of following question given below:
Question: A football is kicked from the ground and clears the goal post by 5 ft. Assume initial angle of 45 degrees.
Part I: How fast will the football have to be kicked if the ball is 52 yards from the goalpost? (Hint: Crossbar on goal post is 10 feet above the field).
Part II: How long did it take to fly through the air?
It'd be really helpful if you could show all steps of your work.
Two identical clocks are synchronized. One is then put in orbitdirected eastward around the Earth while the other remains on the Earth. Which clock runs slower? When the moving clock returns tothe Earth, are the two still synchronized?
