Chapter 5, Problem 5.9CYU
Check Your Understanding One end of a 3.0-m rope is tied to a tree; the other, end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 0.25 m. If he exerts a force of 200.0 N under these conditions, determine the force exerted on the car.

- Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle?

You have a choice of (a) pushing her from behind, by applying a force downward on her shoulders at 30 below the horizontal (Fig. 5.2a) or (b) attaching a rope to the front of the sled and pulling with a force at 30 above the horizontal (Fig 5.2b). Which would be easier for you and why?arrow_forward
- Two forces pull on a body that rests on a smooth horizontal surface: One is 30 N 50o S of E and the other is 40 N 45o S of W. Determine the resultant of the two forces using the triangle method.arrow_forwardOn her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical? The whole question did not paste in on my last attempt.arrow_forwardA block of wood of mass 5 kg rests on a horizontal surface. If a horizontal force of 20N is applied to the block and the block is still at rest, calculate the following: (a) the friction force between the surface and the block. (b) the normal force on the block. (C) the coefficient of static friction.arrow_forward
- A horse is harnessed to a sled having a mass of 236 kg, including supplies. The horse must exert a force exceeding 1 240 N at an angle of 35.0o in order to get the sled moving. Treat the sled as a point particle, (a) Calculate the normal force is 1 240 N. (b) and the coefficient of static friction between sled and the ground beneath it. (c) Find the static frirction force when the horse is exerting a force of 6.20×102 N on the sled at the same angle.arrow_forwardOn her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical? I was given the WRONG answer this morning! The force that Red applied was 13.5N NOT 12.2 N! Use 13.5 N! I use this service primarily to check my work. If the "experts" are using the wrong values, I question if they will use the right mathematical procedures if I really have a challenge!arrow_forwardConsider the 52.0-kg mountain climber shown below.
