When a 1.50-kg dress hangs midway from a taut clothesline stretched between two poles planted 7.50 m apart, the clothesline is seen to sag 0.0500 m. a. Draw a free-body diagram of the dress. b. What is the tension produced on the clothesline by the dress? Assume the clothesline is massless.
Integrated Concepts When starting a foot race, a 70.0-kg sprinter exerts an average force of 650 N backward on the ground for 0.800 s. (a) What is his final speed? (b) How far does he travel?
Jogging on hard surfaces with insufficiently padded shoes produces large forces in the feet and legs. (a) Calculate the magnitude of the force needed to stop the downward motion of a jogger's leg, if his leg has a mass of 13.0 kg, a speed of 6.00 m/s, and stops in a distance of 1.50 cm. (Be certain to include the weight of the 75.0-kg jogger's body.) (b) Compare this force with the weight of the jogger.
A 76.0-kg person is being pulled away from a burning building as shown in Figure 4.41. Calculate the tension in the two ropes if the person is momentarily motionless. Include a free-body diagram in your solution. Figure 4.41 the force T2 needed to hold steady the person being rescued from the fire is less than her weight and less than the force T1 in the other rope, since the more vertical rope supports a greater part of her weight (a vertical force).
A motorcycle and rider have a total mass equal to 300 kg. The rider applies the brakes, causing the motorcycle to accelerate at a rate of 5 m/s2. What is the net force on the motorcycle?
You press your physics textbook flat against a vertical wall with your hand. What is the direction of the friction force exerted by the wall on the book? (a) downward (b) upward (c) out from the wall (d) into the wall
Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?
A weight lifter stands on a bathroom scale. He pumps a barbell up and down. What happens to the reading on the scale as he does so? What If? What if he is strong enough to actually throw the barbell upward? How does the reading on the scale vary now?
. A person stands on a scale inside an elevator at rest (Figure 2.54). The scale reads 800 N. (a) What is the person's mass? (b) The elevator accelerates upward momentarily at the rate of 2 m/s2. What does the scale read then? (c) The elevator then moves with a steady speed of 5 m/s. What does the scale read now?
Train Collision and Newtons First Law A group of college students discusses the train collision case study. Use Newtons first law to decide which underlined statements are correct and which are false. Explain your answers. Shannon: This newspaper says that the people who got really hurt were either standing up or sitting in a forward-facing seat. Those people got thrown forward when the train stopped. Avi: Thats why there are seat belts in cars. If you get into a crash, the force can throw you through the windshield. Cameron: There is no force that throws you through the windshield. You fly through the windshield because you are already moving and it would take a force to stop you from going forward. Thats why theres a seat belt. Avi: That doesnt make sense. Because then you would need a force to stop you from flying through the windshield even when you just stop slowly at a red light. Cameron: Thats right, but when you slow down slowly, you dont need such a big force and the car seat can take care of it. Shannon: The seat? I dont think a seat can exert a force. It cant move on its own or hold you. Thats why the people who were sitting forward on the train were hurt. The people who were sitting backward had the back of the seat to block them.
A 17-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall sales. It's a good way to make extra money, and the teen is saving for a car. Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 707 N at an angle of 33.7° above the horizontal to accelerate a 121-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.55. Determine the acceleration experienced by the crate in m/s2. Use the approximation g ≈ 10 m/s2.
(25 points) A box with mass m is placed on top of a box with mass 2m as shown in thefigure. An external force F(t) = αt, where α is a positive constant, acts on the bottomblock and causes it to accelerate from rest at t = 0. The two blocks have coefficient ofstatic friction µ between them, and the bottom box slides on a frictionless surface. Atwhat time will the top block begin to slide relative to the bottom block? It seems like the relationship would just be when F(t) > µmg which would be t = (µmg)/α but the book is saying it would be 3(µmg)/α I know it has to do with the relations of the masses and all that but I cant figure out how to actually solve it
