Suppose a friend asks to examine the 10.0 kg box you were Given, hoping to guess what is inside; and you respond, "sure, pull the box over to you." she then pulls the attached cord along the smooth surface of the table. The magnitude of The force exerted by the person is Fp = 40.0 N, and is exerted at a 30.0o angle.
(a) Calculate the acceleration of the box.
(b) Calculate the magnitude of the upward force FN exerted by the table on the box.
