A 12 kg block is pressed against a spring with spring constant k = 1424 N/m. The spring is normally 65 cm long but the block is pressed against it to compress the spring until it is only 27 cm long. The block is then released and the spring pushes it forward onto a frictionless surface. a)How fast is the block moving immediately after it leaves the spring? b) The mass then slides across a 2.5 m wide surface with...
3. A horizontal 2.50kg block is pressed against a spring with a spring constant of 300N/m, compressing it 25.0cm. The block is released from rest and is pushed until it is no longer in contact with the spring. The coefficient of friction between the block and the floor is 0.400. a. Solve for the energy of the spring. (ans: 9.38 J) b. Solve for the velocity of the block as it leaves the spring. (ans: 2.35 m/s)
A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...
A 2-kg block is pushed against a spring with spring-constant k 512 N/m, compressing it 0.25 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope 53.1° (a) What is the speed of the block as it slides along the horizontal surface after having left the spring? (b) How far does the block travel up the incline before starting to slide back down?
A block of mass 3.40 kg is placed against a horizontal spring of constant k = 865 N/m and pushed so the spring compresses by 0.0600 m. (a) What is the elastic potential energy of the block-spring system (in J)? (b) If the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring.
A block of mass 3.80 kg is placed against a horizontal spring of constant k = 865 N/m and pushed so the spring compresses by 0.0800 m.

In the figure(Figure 1) a 1.5 kg block is held at rest against a spring with a force constant k = 720 N/m . Initially, the spring is compressed a distance d. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 5.0 cm that has a coefficient of kinetic friction μk = 0.45. Part A Find d such that the block's speed after crossing the rough patch is 2.4...
