3М Before 2. Two blocks of masses M and 3M are placed on a horizontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them (see figure). A cord initially holding the blocks together is burned, after this, the block of mass 3M moves to the right with a speed of 2.00 m/s. (a) What is the speed of the block of mass M? (b) Find the original...

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...

Two blocks on a frictionless table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring has a spring constant of 215N / m and was compressed by 0.20 m. If one of the blocks moves at 1.50 m/s and the other moves away at 3.00 m/s , what is the mass of the heavier block in kg? (Hint: mechanical energy in...

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...

O Question 10 Two blocks on a frictionless table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in agaosite directions. The spring was compressed by 0.05 m. One of the blocks moves away at 0.28 m/s while the other moves away at 0.56 m/s. The heavier of the two blocks has a mass of 0.75kg. What is the spring constant in N/m?/Hint mechanical energy in...

A 0.45 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 24.0 N/m. Let x be the displacement, where x = o is the equilibrium position and x > 0 when the spring is stretched. The object is pushed, and the spring compressed, until хі =-4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the object's maximum speed (in m/s) after it is...
