- If the coefficient of static friction between all surfaces in contact is µg = 0.3 and a determine force P that must be applied to wedge A in order to lift the block weighing 500 N. The weight of wedge A is negligible compared to the block. B PA 32.7-kg crate rests on a horizontal floor, and a 62.0-kg person is standing on the crate. Determine the magnitude of the normal force that (a) the floor exerts on the crate and (b) the crate exerts on the person.A box-shaped of mass 5.2 kg is hung against a building, resting against the wall and suspended on a rope oriented at theta=37 degrees. a) find the magnitude of the normal force acting on the box b) determine the tension in the rope c) What is the magnitude of force on the wall exerted by the box?
- Three rugby players are pulling horizontally on ropes attached to a box, which remains stationary. Player 1 exerts a force F equal to 200 N at an angle 0, equal to –60.0° with respect to the +x-direction, as shown in the figure. Player 2 exerts a force F2 equal to 300 N at an angle 02 equal to 37.0° with respect to the +x-direction. The view in the figure is from above. Ignore friction and note that gravity can be ignored in this problem. Determine the force F3 exerted by player 3. State your answer by giving the x- and y-components, F3, and Fay, respectively. F, F3x -339.59 N F3y N Player 3's rope breaks, and player 2 adjusts by pulling with a force of magnitude F; equal to 250 N at the same angle as before. Defining angles above the x-axis as positive and those below as negative, at what angle 0 is the acceleration of the box relative to the +x-direction? The magnitude of the acceleration is measured to be 10.0 m/s?. What is the mass m of the box? kg m = F TOOLS x10Problem 8: A crate of mass m =29.1 kg is in the bed of a pickup truck with the tailgate closed. There is Acceleration Tailgate negligible friction between the horizontal bed and the crate. The tailgate is vertical and contacts the back side of the crate. The truck accelerates forward on horizontal ground at a rate a =2.1 m/s². BedA 37 N block rests on an inclined plane with a slope of 25°. What is the normal force acting on the block?
- As shown in the figure, a woman is straining to lift a large crate, but without success because it is too heavy. We denote the forces on the crate as follows: P is the magnitude of the upward force being exerted on the crate by the person, C is the magnitude of the vertical contact force on the crate by the floor, and W is the weight of the crate. How are the magnitudes of these forces related while the person is trying unsuccessfully to lift the crate? OA P=C OB.P+C>W OCP+CTwo Physics 101 students are attempting to remove an old stump from the ground. They start by hammering a spike into the stump to give them something to tie on ropes. Assume that both students pull with the same force and rank the following strategies from most to least effective (most effective in the #1 spot). Question 1 options: Tie on one rope and have both students pull on it. Tie on two ropes and have each student pull with a 15 degree angle between the ropes. Tie on two ropes and have each student pull with a 45 degree angle between the ropes. Tie on two ropes and have each student pull with a 60 degree angle between the ropes.Give an example of a situation in which an object is not in equilibrium, even though the net force acting it is zero.
