Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

**Text:**

A 100 kg one-man bobsled starts from rest 50 m from the end of an icy, 15° slope. A giant 2.0-m-long spring is placed against a barricade at the bottom of the slope. *(Figure 1)* shows a coordinate system with the origin at the base of the spring. The bobsled brake fails to work, and the sled crashes into the spring. The spring compresses 75 cm before expanding and shooting the bobsled back up the slope. What is the spring constant of the spring?

**Figure Explanation:**

The figure illustrates a sloped surface inclined at an angle of 15°. At the bottom of the slope, there is a coiled spring located against a vertical barricade. The slope is smooth and icy, implying minimal friction. The coordinate system is established with the x-axis running along the slope and the y-axis perpendicular to it, originating at the base of the spring. The drawing depicts a bobsled poised on the slope, preparing to descend toward the spring.

Superman wanted to launch a small rocket using a spring mounted vertically on the ground. He placed the 4.0 kg rocket on a very stiff spring. The spring is 1.5m long, it has negligible mass and a spring force constant of 100,000 N/m. He compresses the spring for 1.1m. He then releases the spring. If y = 0 at the ground level, the system consists of the rocket and the spring; (I) what is the energy of the system before Superman releases the rocket? (II)What is the maximum height the rocket can reach if we can neglect air resistance? (III) If air resistance can’t be neglected, it exerts a constant force of 37.5N on the rocket, how high will the rocket reach? (IV) What is the speed of the rocket when it is 120.0 m from the ground if air resistance is taken into account?
Two 2 kg carts are connected by a compressed spring of stiffness 5 J/cm2. Starting from rest, the spring decompresses by 1 cm, sending the carts in opposite directions. a) What is the speed of each of the carts after the spring is released?
A spring with spring constant 23 N/m is compressed a distance of 8.0 cm by a ball with a mass of 219.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 8.0 cm and is also released, leaving the spring at point A. Assume the ball rolls, but ignore other effects of friction. (Assume that the ball is a solid ball.) (a) What is the speed of the ball at point B?(b) What is the speed of the block at point B?
If a 4-kg block is placed against the spring and the spring is released, what will be the speed of the block when it separates from the spring at x =0? Neglect any friction in the problem.
A 0.250 kg dart is fired into a stationary 1.20 kg block of wood that is on a frictionless surface (of course!). The dart and block then impact a spring with a spring constant of k = 1120 N/m and compresses it 0.360 m. (Use g = 10 m/s2, as needed. Do not enter units in numerical answers.) What is the total energy stored in the spring, in Joules, when it is fully compressed? ____ What is the speed, in m/s, of the dart-block combination after the collision? ____ How fast was the dart moving, in m/s, before it hit the block of wood?

A 0.100 kg block of ice is placed against a horizontal, compressed spring mounted on a horizontal tabletop that is 1.50 m above the floor. The spring has force constant 2000 N/m and is initially compressed 0.045 m. The mass of the spring is negligible. The spring is released, and the block slides along the table, goes off the edge, and travels to the floor. If there is negligible friction between the block of ice and the tabletop, what is the speed of the block of ice when it reaches the floor?
In a needle biopsy, a narrow strip of tissue is extracted from a patient with a hollow needle. Rather than being pushed by hand, to ensure a clean cut the needle can be fired into the patient's body by a spring. Assume the needle has mass 5.60 g, the light spring has force constant 440 N/m, and the spring is originally compressed 8.10 cm to project the needle horizontally without friction. (The spring is fully uncompressed before the needle contacts the skin.) The tip of the needle then moves through 2.40 cm of skin and soft tissue, which exerts a resistive force of 7.50 N on it. Next, the needle cuts 3.50 cm into an organ, which exerts a backward force of 9.70 N on it. (a) Find the maximum speed of the needle. m/s(b) Find the speed at which a flange on the back end of the needle runs into a stop, set to limit the penetration to 5.90 cm. m/s
