Compute all parts of given problem:
Problem: An object, which is initially at rest on a frictionless horizontal surface, is acted upon by four constant forces. F1 is 18.1 N acting due East, F2 is 41.2 N acting due North, F3 is 43.5 N acting due west, and F4 is 14.1 N acting due south.
Part A: How much total work is done on the object in 4.44 seconds, if it has a mass of 12.0 kg?
Part B: How fast does the object end up moving at the end of the 4.44 seconds?
I need help to find how fast the object ends up moving at the end of the 4.44 seconds.
