An experiment is done on a horizontal surface. A block of mass m_1 is initially held in place compressing a spring with spring constant k by a distance x_0. The other end of the spring is firmly attached to the wall and does not move. What is the final speed of m_1 after it is released and loses contact with the spring? After it reaches its final speed, m_1 collides and sticks to a second block of mass m_2. What...

Question 7 A 0.73 kg block is placed on a horizontal surface with a coefficient of kinetic friction of 0.122. The block is pressed against a spring that has a spring constant of 683 N/m until it has compressed the spring by 13.7 cm. When the block is allowed to move freely, the spring pushes the block 10 cm along the horizontal surface at which point it encounters an upward slope with an angle of 29.0°. This slope has the...

A spring is mounted horizontally. A crate, which has a mass of 8.5 kg is pressed against the spring with a force of 350N As a result the spring is compressed a distance of 82.0 cm The mass is then released and is allowed to slide along the horizontal surface which has friction. The coefficient of kinetic friction between the crate and the surface is 0.65 How much work will be done on the crate by the frictional force from...

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 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...
