**A mass m2 = 1.5 kg is initially moving with velocity vo. It collides completely inelastically with a block of mass m2 = 2.0 kg. The second block is attached to a spring with a spring constant of k = 5.6x10ʻN/m. The
block and spring lie on a frictionless horizontal surface. The spring compresses a distance of 0.20 m upon
collision
(a) What is the velocity of the mass mi and the block immediately after the collision?
(b) What is the initial velocity of the mass mi immediately before the collision?
(C) If the block were attached to a long string and hung as a pendulum, how high would the block and mass
mi rise after the collision?
