3. Two blocks of masses m and 3m are placed on a frictionless horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together and connected with a cord. The spring has a spring constant k, and while the blocks are pushed together, the spring is compressed over a distance d. At a moment in time t-0, the cord is cut, the spring expunds, and the blocks are sliding away from each other....

Two blocks with masses 0.90 kg and 3.90 kg are placed on a horizontal frictionless surface. A light spring is placed in a horizontal position between the blocks. The blocks are pushed together, compressing the spring, and then released from rest. After the blocks lose contact with the spring ends, the 3.90 kg mass has a speed of 1.00 m/s. The combined final kinetic energies of the blocks was originally stored in the spring. Determine how much potential energy was...

4. Two blocks with masses 10.0 kg and 15.0 kg are placed on a horizontal frictionless surface. A light spring is placed in a horizontal position between the blocks. The blocks are pushed together, compressing the spring, and then release from rest. After blocks have lost contact with the spring, the 10.0 kg mass has velocity, v = 4.0 î m/s. (a) How much potential energy was stored in the spring before the blocks were released? (b) What is the...

Two blocks are connected by a massless rope slung over a massless, frictionless pulley at the edge of a table. One block moves horizontally along the tabletop; it has a mass of 8.00 kg. The other block is freely-hanging off the edge of the pulley; it has a mass of 6.00 kg. Initially, both blocks have a speed of 0.900 m/s; the blocks come to rest after they have moved 2.00 m. What is the coefficient of kinetic friction between...

Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.105 kg, initially moves to the right at a speed of 4.50 m/s, while the second block, of mass 0.210 kg, is initially to the left of the first block and moving to the right at 7.10 m/s. Find the final velocities of the blocks, assuming the collision is elastic. velocity of the 0.105 kg block = velocity of the 0.210 kg block...

Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.116 kg, initially moves to the right at a speed of 5.20 m/s, while the second block, of mass 0.232 kg, is initially to the left of the first block and moving to the right at 7.30 m/s. Find the final velocities of the blocks, assuming the collision is elastic. Velocity of the .116 kg block to the right: Velocity fo the .232...

Two blocks are sliding across a horizontal frictionless tabletop. Block A has a mass of 5 kg, and it is sliding directly southward with a speed of 8 m/s. Block B has a mass of 7 kg, and it is sliding directly westward with a speed of 4 m/s. The blocks then collide and stick together. What is the speed of the new combined block after the collision?

Before Collision M m After Collision V/2 M m A block having mass m slides on a frictionless surface and runs into a block of mass M which is initially at rest. The blocks stick together and their speed after the collision is half the speed the moving block had before the collision. How do the masses of the blocks compare? M<m M = m M>m
