Textbook Question
Chapter 5, Problem 16RQ
You weigh 100 pounds, your friend weighs 200 pounds, and you are in an arm wrestling contest with each other. Neither person is winning, but each of you is struggling to push the other’s forearm over to the tabletop. Which of Newton’s laws applies to this scenario and why? Now in one swift motion you plant your friend’s forearm on the table, winning the contest. Which of Newton’s laws applies to this motion and why?

Two people play tug of war. The 100-kg person on the left pulls with 1,200 N, and the 70-kg person on the right pulls with 800 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons?
With bumpers touching, a 3,773 kg truck is pushing a 1,103 kg car. The truck and the car move forward together with a maximum forward force of 18,470 N. Assuming friction is zero, what is the magnitude of the force (in N) of the car's bumper on the truck's bumper?
Hullo, everyone! I actually know the answer to this question, because I keep getting it marked as wrong - the answer is supposed to be 4178, but for the life of me, I can't figure out how. I thought it would be as simple as finding the acceleration, then multiplying by mass, but I've tried converting kg to g, tried the law of equal and oppositie reaction, tried the car's mass, tried the truck's mass, but I never even get close to the answer I've been given. The AI function on Bartleby, which I have often found quite useful, also can't get 4178. If anyone could send me the specific steps involved in getting this answer, I would be so grateful - thank you so much!
've tried everything with this question.
A skydiver weighing 203 lbf (including equipment) falls
vertically downward from an altitude of 5000 ft and
opens the parachute after 14 s of free fall. Assume that
the force of air resistance, which is directed opposite to
the velocity, is 0.77 |v| when the parachute is closed
and 10 |v| when the parachute is open, where the
velocity v is measured in ft/s.
Use g = 32 ft/s². Round your answers to two decimal
places.
(a) Find the speed of the skydiver when the parachute
opens.
v(14) = i
(b) Find the distance fallen before the parachute opens.
x (14) = i
ft
ft/s
(c) What is the limiting velocity after the parachute
opens?

In fact, if you are standing on a bathroom scale at the time, the scale measures a force having a magnitude that is greater than your weight. Therefore, you have tactile and measured evidence that leads you to believe you are heavier in this situation. Are you heavier?arrow_forwardQUESTION 1: If you can exert a pull that is greater than your weight, why can’t you fly off the ground by pulling your belt upward? because the Earth will pull you downward with the same force, so they cancel out because your body exerts the same amount of force on you, so they cancel out because the normal force and your weight cancel out just before you pull your belt upward not enough information is given QUESTION 2: You are pushing a box to the right with a 210-N force. How much force does the box exert on you? less than 210 N, to the left equal to 210 N, to the left equal to 210 N, to the right greater than 210 N, to the leftarrow_forward

- An accident victim with a broken leg is being placed in traction. The patient wears a special boot with a pulley attached to the sole. The foot and boot together have a mass of 4.0 kgkg, and the doctor has decided to hang a m� = 6.6 kgkg mass from the rope. The boot is held suspended by the ropes and does not touch the bed. (Figure 1) Determine the amount of tension in the rope by using Newton’s laws to analyze the hanging mass. Assume that ϕ� = 11 ∘∘ .Hint: If the pulleys are frictionless, which we will assume, the tension in the rope is constant from one end to the other. The net traction force needs to pull straight out on the leg. What is the proper angle θ� for the upper rope? What is the net traction force pulling on the leg?arrow_forwardConsider the Washington Monument in Washington, D.C. in the United States.
