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 37.0 N acting due North, F3 is 39.2 N acting due West, and F4 is 27.3 N acting due South. How much total work is done on the object in 3.33 seconds, if it has a mass of 18.0 kg?
Which type of energy is changing for the object while the above work is being done?
A) internal energy
B) gravitational potiential energy
c) elestac potential energy
D) kinetic energy
How fast does the object end up moving at the end of the 3.33 seconds?
