Solve the all parts of given question:
Question: A catcher catches a 145g baseball traveling horizontally at 32.0m/s
Part I: How much work does the pull do on the box?
Part II: Suppose that the same pull is exerted at an angle above the horizontal. If this pull now does 56.0J of work on the box while pulling it through the same distance, what angle does the force make with the horizontal?
Show all work, use additional paper if necessary.
