A spring with k=130.0 N/m on surface is mounted to a vertical wall. A 5.00-kg box on the surface is placed in front of the spring. The coefficient of kinetic friction between the box and the surface is ylik = 0.400. A constant force F is applied to the box. F has magnitude 89.0 N and is directed against the wall. The spring is compressed 80.0 cm. Problem 5 Express your answer with the appropriate units. A spring with k=130.0...

6. Consider a horizontal spring with spring constant k. A block with mass m is pushed far to the left against the spring until the spring is compressed a distance r relative to its relaxed length. A second block, which is stationary and also has a mass m, is located to the right of the spring im rrm a) We release the first block from rest. Due to the force from the spring, it slides to the right and eventually...

A) A 50.0 kg box rests on a horizontal surface. The coefficients of static and kinetic friction between the box and the surface are 0.300 and 0.200, respectively. What is the friction force on the box if a horizontal 175 N push is applied to it? Explain. B) A horizontal force of 250 N is applied to the box. After the box moves a distance d from rest, the speed of the box is measured to be 6.4 m/s. use...

a box will be launched on a horizontal surface using a spring. the spring has a spring constant of 11n/m. the box is pressed against the spring, compressing it by 0.25m. the coefficient of kinetic friction between the box and the surface is 0.10.a) how fast is the box moving when it leaves the spring. B)how far from the compressed spring does the box slide.

A 14 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 5.7 kN/m. The block is pulled to the right so that the spring is stretched 15 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 44 N. (a) What is the kinetic energy of the block when it has moved 3.0 cm from...

A light spring of force constant 3.90 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.520 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is the following. In each case, assume...

A Red Rider bb gun uses the energy in a compressed spring to provide the kinetic energy for propelling a small pellet of mass 0.26 grams. By cocking the lever attached to the stock of the rifle, the spring (k = 2000 N/m) is compressed 9.5 cm from its equilibrium point. What is the potential energy energy stored in the compressed spring? A: 3.6966 B: 4.6208 C: 5.7760 D: 7.2200 E: 9.0250 J What is the kinetic energy of the...

7: A 60-kg box is placed against a uniform spring with a spring constant (k) of 3300 N/m The box is pushed to the right so it compresses the spring 25-cm. When the box is released, it is propelled to the left. (a) What is the velocity of the box as it slides along the flat surface to the left after it loses contact with the spring? 350 (b) How far up the ramp will the box slide while coming...
