The spring provided in the
image has an unstretched length of 60 cm. If it is confined by a
small plate and awall, so that the length of confinement is 50 cm,
determine the initial speed of the 2 kg block in A. Assume that the
spring is farther compressed 5 cm when the block momentarily stops.
The stiffness constant of the spring is 35 N/m.
feel free to drop comment if you have any doubt.

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...
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...
Review The spring has a stiffness k = 50 N/m and an unstretched length of 0.3 m It is attached to the 2.8-kg smooth collar and the collar is released from rest at A (@= 0°). The motion occurs in the horizontal plane. Neglect the size of the collar. (Figure 1) Part A Determine the speed of the collar when = 60° Express your answer to three significant figures and include the appropriate units. Figure < 1 of 1 >...
A relaxed spring of length 0.19 m stands vertically on the floor; its stiffness is 1270 N/m. You release a block of mass 0.5 kg from rest, with the bottom of the block 0.7 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring? m
A relaxed spring of length 0.17 m stands vertically on the floor; its stiffness is 1460 N/m. You release a block of mass 0.6 kg from rest, with the bottom of the block 0.4 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring?

An Unstretched spring with a spring constant of 19.6 N/m is attached to a 2.6 kg block at rest on a horizontal table. A constant 23.6 N force is applied to stretch the spring 41 cm from its resting position. After being let go, what is the speed of the block as it passes equilibrium? A. 3.4 m/s B. 3.1 m/s C. 2.5 m/s D. 7.8 m/s
