Amassless spring with force constant 602 n/m is fastened at its left end to a vertical wall, as shown below. initially, the 6 kg block and 3 kg block rest on a horizontal surface with the 6 kg block in contact with the spring (but not compressing it) and with the 3 kg block in contact with the 6 kg block. the 6 kg block is then moved to the left, compressing the spring a distance of 0.6 m, and held in place while the 3 kg block remains at rest as shown below. the acceleration of gravity is 9.8 m/s2
a) determine the elastic energy u stored in the compressed spring. answer in units of j ?
b) the 6 kg block is then released and accelerates to the right, toward the 3 kg block. the surface is rough and the coefficient of friction between each block and the surface is 0.3 . the two blocks collide, stick together, and move to the right. remember that the spring is not attached to the 6 kg block. find the speed of the 6 kg block just before it collides with the 3 kg block. ? answer in units of m/s.
c) find the final speed of both blocks (stuck together) just after they collide. answer in units of m/s?
d) find the horizontal distance the blocks move before coming to rest. answer in units of m ?
