2. A 60kg box is dragged across a horizontal floor by means of a rope. The coefficient of friction between the box and the floor is 0.298. If the angle between the rope and the floor is 40°, how much force must be exerted on the rope to move the box at constant speed? Note: Please show your solutions clearly and draw FBD.

Thank you. Can you just explain specifically how Newton's 2nd and 3rd Law apply to the egg drop situations. Is the force the same in all instances, depending on the height and why? And does te eforce balance out in all three cases when it hits the ground-why is this so for Newton's 3rd Law?
