I don't understand why Fs <= Fk. What does the F in (1) and (2) stand for? If it's force applied, wouldn't F = Fs + Fk for box 2, and (F - Fs - Fk) = Fs for box 1? My thinking is that the Force applied on box 2 minus the force of kinetic friction and the force of static friction applied by Box 1 on 2 would equal to the net force. Then the net force of box 2 would cause the same netforce on box 1, if box 1 isn't moving, then it's Fs should be equal to that net force applied on box 1. Therefore Force applied wouldn't be equal to Static Friction Force, and shouldn't it be bigger than the Kinetic Friction Force since it's moving in the direction of Force applied?
If the rocket sled shown in the previous problem starts with only one rocket burning, what is the magnitude of this acceleration? Assume that the mass of the system is 2.10103kg , the thrust Tis 2.40104N , and the force of friction opposing the motion is 650.0 N. (b) Why is the acceleration n one-fourth of what it is with all rockets burning?
Compute the acceleration of each mass in the figure below, and the tension in the rope. Let m1 = 1.24 kg and m2 = 2.04 kg.
Three stacked blocks are placed in an elevator as shown: Assume the stack of blocks is in contact with the floor of the elevator. If m = 11.9 kg and the elevator is accelerating upward at 1.9 m/s2, what is the normal force exerted on the 5m block by the 8m block? Express your answer in N, to at least one digit after the decimal point.
A body with a mass of 5 kg rests on a rough horizontal table with a coefficient of static friction of 0.9. At a given moment, a horizontal force of 40 N is applied to this body, as shown in the figure. Analyze the propositions and answer the alternative that corresponds to the sum of the correct ones. Adopt g = 10 m/s². (01) With the data presented, we can conclude that the static friction force is 48 N. (02) In the proposed situation, the body will move with an acceleration of 5 m/s2. (04) In the proposed situation, the body will not move. (08) In the proposed situation, the body will be subjected to a frictional force of 40 N.

A person working out, with arms stretched out to either side, holds 5 kg in each hand. Whilesitting on a spinning stool, he is spun around by a helpful friend. What will happen to hisangular speed, if anything, when he lets the weights fall to the floor? Explain in detail youranswer.
Hi! Please ndicate the given, diagram, FBD, and the solution with no shortcuts, Thanks! 5) A body system has three forces which are all at rest and in equilibrium. F1 is measured at 170 N whilst F3 is equal to340 N. The direction of each force is shown in the figure below. To balance the force within the body system, computefor the magnitude of F2 and its direction.
How do I solve for the answer to this question? An applied force of 41 N causes a 7.5 kg box to accelerate at a rate of +2.8 m/s2 across a table.-What is the coefficent of friction?-What is the net force?-What is the normal force?-What is the force of gravity (weight)?
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?
Consider the baby being weighed in the following figure. (a) What is the mass of the infant and basket if a scale reading of 55 N is observed?
