Part A The spring has a stiffness k 50 lb/ft and an unstretched length of 2 ft. As shown, it is confined by the plate and wall using cables so that its length is 1.5 ft. A 4.1-lb block is given a speed vA when it is at A, and it slides down the incline having a coefficient of kinetic friction fk -0.2. It strikes the plate and pushes it forward 0.25 ft before stopping. Neglect the mass of the...
The spring has a stiffness of k = 50 lb/ft and an unstretched length of 2.00 feet. As shown, it is confined by the plate and wall using cables so that its length is 1.5 feet. An 8 pound block is given a speed VA, when it is at A, and it slides down the incline having a coefficient of friction of 0.40. If it strikes the plate and pushes it forward 0.40 feet before stopping, determine its speed at...
The spring bumper is used to arrest the motion of the 8 lb block, which is sliding toward it at 5 ft/s . As shown, the spring is confined by the plate P and wall using cables so that its length is 1.5 ft. (Figure 1) Part A If the stiffness of the spring is k = 50 lb/ft, determine the required unstretched length of the spring so that the plate is not displaced more than 0.2 ft after the...

As shown, the spring is confined by the plate P and wall using cables so that its length is 1.5 ft. (Figure 1) Part A Figure 1 of 1 > If the stiffness of the spring is k = 50 lb/ft, determine the required unstretched length of the spring so that the plate is not displaced more...
The spring bumper is used to arrest the motion of the 9 lb block, which is sliding toward it at 5 ft/s . As shown, the spring is confined by the plate P and wall using cables so that its length is 1.5 ft. If the stiffness of the spring is k = 50 lb/ft, determine the required unstretched length of the spring so that the plate is not displaced more than 0.2 ft after the block collides into it....
