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...

Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
