A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?

A 2.1.0-kg block is accelerated from rest by a compressed spring (ks = 545 N/m). The block leaves the spring at the spring’s relaxed length. The block then travels along a rough horizontal with a coefficient of kinetic friction μk = 0.240 a distance of x = 6.90 m before frictional force stops the block. What was the original compression distance of the spring?

Problem 5 A spring with a spring constant k=200 N/m is used as a launcher for a small block whose mass is 10 g. The block is placed against the compressed spring in a horizontal arrangement on a smooth horizontal surface. The spring, with the block, is compressed 5 cm and then released. a) Find the speed of the block just as it leaves the spring b) The block encounters a rough surface as it leaves the spring. How much...

If the horizontal surface has a coefficient of kinetic friction
μk=0.500, what is the maximum compression of the spring?
An 8.0-9 bullet is shot into a 5.0-kg block, at rest on a frictionless horizontal surface (see the figure). The bullet remains lodged in the block and the bullet-block system moves to the right with speed V. The bullet-block system moves into an ideal massless spring and compresses it by 8.7 cm. The spring constant of the spring is 1200 N/m....

3. (10pts) A spring, with a spring constant of 5710 N/m, is compressed by 0.45 m and used to launch a 15.5 kg mass from rest from point A across a frictionless surface and down a short hill that is H = 1.73 m high. The surface becomes rough at point B, and the mass comes to a stop at point C. (a) (5pts) How much work was done by friction between B and C? (b) (5pts) If the coefficient...

A horizontal spring with force constant k = 700 N/m is attached to a wall at one end and to a block of mass m = 2.30 kg at the other end that rests on a horizontal surface. The block is released from rest from a position 3.40 cm beyond the spring's equilibrium position. (a) If the surface is frictionless, what is the speed of the block as it passes through the equilibrium position? m/s (b) If the surface is...

A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up...
