Question
In the figure, block 2 (mass 1.60 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 161 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.10 kg), traveling at speed v1 = 4.90 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?The figure is block 1 moving with a velocity v1 towards block2 which is attached to a spring that is also attached to a wall.
Explanation / Answer
0.5 * 1.1 * 4.9 ^2 = 0.5 * k * x^2 thus x = 40.5 cm
